Microsoft Agent 365 vs Salesforce Agentforce vs Glean for Enterprise AI Agents

Key Takeaways

Microsoft Agent 365 is a governance and control plane for AI agents across an organization’s entire fleet, not a standalone AI assistant. It became generally available in May 2026 and is bundled into the Microsoft 365 E7 Frontier Suite at $99/user/month.
Salesforce Agentforce hit $540M ARR, growing 330% year-over-year, but only about 8% of Salesforce’s 150,000+ customers have adopted it so far.
Glean doubled its ARR to $200 million in roughly nine months, reaching a $7.2 billion valuation after a $150M Series F in June 2025.
Glean is an Agent 365 launch partner, meaning all three platforms can coexist, and Glean’s search context now surfaces inside Microsoft Word, Outlook, and Teams.
Microsoft 365 Copilot covers only the Microsoft ecosystem by default. It cannot natively search Slack, Confluence, Jira, or Salesforce without extra connectors and licensing layers.
Agentforce requires clean, structured CRM data to function reliably. 77% of B2B deployments report failures tied directly to data quality problems and CRM hygiene issues.
Only 6% of organizations that piloted Microsoft 365 Copilot moved to broader deployment, according to Gartner, a figure that reflects the tool’s narrow ecosystem fit for mixed-stack organizations.
Agentforce now offers three concurrent pricing models: $2/conversation, $0.10/action via Flex Credits, and per-user licenses starting at $125/user/month, creating real budget predictability challenges.
Glean connects to 100+ enterprise applications, including both Google Workspace and Microsoft 365, making it the most stack-agnostic of the three platforms.

Picking an enterprise AI agent platform in 2025 and 2026 is less a product decision and more an architectural one. The three major players, Microsoft with its Agent 365 and Copilot ecosystem, Salesforce Agentforce, and Glean’s Work AI platform, each solve a genuinely different problem. Using the wrong one for your use case means months of expensive rework, not just a feature gap.

This article breaks down what each platform actually does, where each one excels, where each falls short, and how to match them to your organization’s real situation. The primary keyword people search is microsoft agent 365 vs agentforce, but Glean belongs in this conversation because it now integrates with Agent 365 and competes directly for enterprise AI agent budgets.

What Each Platform Actually Is

Before comparing features, it helps to be clear on the category each product occupies, because they are not direct substitutes.

Microsoft Agent 365

Microsoft Agent 365 is a control plane for AI agents across an enterprise, not an AI assistant you use day-to-day. Think of it as the management layer that gives IT, security, and business teams the ability to observe, govern, and secure every agent running in an organization, including agents built by Microsoft, by third-party vendors, and by internal developers.

It became generally available on May 1, 2026, and is bundled into the Microsoft 365 E7 Frontier Suite alongside Microsoft 365 E5, Microsoft 365 Copilot, and the Microsoft Entra Suite. The E7 bundle costs $99 per user per month, which Microsoft positions as a 15% discount versus buying the components separately.

Agent 365 provides:

A central agent registry with real-time dashboards covering total agents, active users, growth trends, runtime hours, and risk signals
Lifecycle governance: install, publish, block, unblock, delete, and reassign agent ownership from a single console
Cross-cloud registry sync with AWS Bedrock and Google Cloud, so IT teams can discover and manage agents running outside Azure
Shadow AI detection via integration with Microsoft Defender and Intune, surfacing local agents running on Windows devices
Granular rollout controls, assigning agents to no users, all users, or specific groups

The AI assistant layer within the Microsoft ecosystem is Microsoft 365 Copilot, which runs inside Teams, Outlook, Word, Excel, and SharePoint. Copilot is powered by OpenAI and Anthropic models and is available as an add-on at $30 per user per month on top of an existing Microsoft 365 Enterprise license. Copilot Studio is the separate, low-code builder for custom agents, priced on a consumption basis using message credits.

Salesforce Agentforce

Salesforce Agentforce is a CRM-native AI agent platform. It runs inside the Salesforce platform and uses what Salesforce calls the Atlas Reasoning Engine to let agents autonomously process customer records, pipeline data, case histories, and real-time behavioral signals from Salesforce Data Cloud.

The mental model for Agentforce is AI that executes business processes, not AI that helps employees write documents. An Agentforce agent can qualify a lead, route a support case, draft a quote, or trigger a downstream workflow, all without a human in the loop. Agentforce launched generally available in October 2024 and has since gone through multiple pricing model changes.

Glean

Glean started as an enterprise search platform and has evolved into what it calls a Work AI platform. Its architecture centers on a permissions-aware knowledge graph that indexes data across 100+ enterprise applications, including Slack, Confluence, Jira, GitHub, Google Drive, Microsoft 365, Salesforce, ServiceNow, Notion, Box, and Dropbox.

Glean’s Agentic Engine 2 now enables agents that can plan, reason, take actions across connected apps, and orchestrate sub-agents. It supports 15+ LLMs through Amazon Bedrock, Azure OpenAI, and Google Vertex, making it the most model-agnostic option in this comparison. Glean announced a partnership with Microsoft in November 2025, becoming a launch partner for Agent 365 and making its agents available inside Word, Outlook, and Teams.

Pricing Breakdown

Microsoft Agent 365 and Copilot Pricing

Microsoft’s pricing structure has several layers:

Microsoft 365 E3: approximately $36/user/month (required base license)
Microsoft 365 Copilot add-on: $30/user/month
Microsoft 365 E7 Frontier Suite (bundles E5 + Copilot + Entra Suite + Agent 365): $99/user/month, available from May 2026
Copilot Studio agents: metered pricing based on message consumption

For organizations already on Microsoft 365, Copilot licensing is a toggle and has low deployment friction. Agent 365 is effectively a governance layer included in E7, so for shops already upgrading to E5-level functionality, the marginal cost to add agent governance is minimal.

Salesforce Agentforce Pricing

Agentforce has cycled through three pricing models since its launch, as SaaStr documented in detail:

Original model: $2 per conversation
Flex Credits (May 2025): $0.10 per action, sold in packages of 100,000 credits for $500
Per-user licenses: $125/user/month for Sales, Service, and Field Service agents
Agentforce 1 Edition: starting at $550/user/month for the full AI suite

All three models run simultaneously. Large enterprises can negotiate pre-commit discounts, but unpredictable consumption-based costs remain a real concern for finance teams. The mandatory Salesforce Data Cloud subscription adds further cost for organizations that want Agentforce to operate at full capability.

Glean Pricing

Glean does not publish pricing publicly. Industry estimates place base licensing at $45-$50/user/month with an additional $15/user/month AI add-on. Enterprise minimums are typically 100 seats, and the median annual deal size is approximately $65,000.

Beyond licensing, full enterprise deployments commonly incur cloud hosting costs of $10,000 or more per month, $20,000-$50,000 in implementation services, and $80,000-$120,000 annually for administrative overhead. A fully loaded Glean deployment for 1,500 seats can approach $350,000-$480,000 per year when all costs are counted.

Where Microsoft Agent 365 and Copilot Excel

If your organization is a deep Microsoft shop, meaning Teams is your primary communication layer, SharePoint hosts your documents, and Outlook is where work happens, Microsoft 365 Copilot is a natural fit. Deployment friction is genuinely low. There is no new tool to install, no connector configuration, and no separate search index to build. It inherits Microsoft’s security, compliance, and data residency infrastructure, which matters greatly for regulated industries like financial services or healthcare that are already Microsoft-committed.

Agent 365 gives enterprise IT teams something no other platform in this comparison offers: a unified governance layer that covers every agent in the organization, including agents built by third parties and agents running locally on Windows devices. This shadow AI detection capability is increasingly relevant as employees experiment with their own AI tools outside IT’s line of sight.

The Frontier Suite’s multi-model approach is also notable. Claude from Anthropic is now available in mainline Copilot chat for E7 customers, and the platform operates across Azure OpenAI and other providers without locking customers into a single model provider. For enterprises worried about model dependency, this is a meaningful differentiator versus Agentforce’s heavier reliance on Einstein AI and OpenAI models.

Where Agentforce Excel

Agentforce is the strongest option when your business processes are CRM-centric. Sales qualification, case routing, service escalation, quote generation, and revenue operations automation are all scenarios where Agentforce has native data access and execution context that no other platform can match out of the box.

The Atlas Reasoning Engine gives Agentforce agents the ability to reason over Salesforce Opportunity stages, Case escalation rules, and Data Cloud segments natively. Building equivalent functionality in Copilot Studio would require months of connector development, custom flows, and ongoing maintenance. For organizations where the CRM is the system of record for customer data, that native context translates directly into faster time-to-value for agentic automation.

Agentforce also has a cleaner agent builder for non-technical users in Salesforce-centric organizations. Admins familiar with Flow and Apex can extend agents without learning new tooling. Salesforce’s integration marketplace and partner ecosystem for CRM-adjacent applications is also deep, covering field service, commerce, marketing automation, and industry clouds for healthcare, financial services, and manufacturing.

Where Glean Excels

Glean is the right choice when your organization is not a single-ecosystem shop. Most enterprises run Slack alongside Teams, Confluence alongside SharePoint, GitHub alongside Azure DevOps, and Salesforce alongside other data systems. Glean’s 100+ connector library indexes all of it and gives employees a single search and AI interface across the entire knowledge base.

Glean’s permissions-aware graph means that search results respect the access controls already set in each connected system. An employee searching for information about a confidential project will only see documents they already have permission to read. This is architecturally important: rather than creating a new permission system to manage, Glean inherits and enforces the ones that already exist.

Glean’s November 2025 integration with Microsoft Agent 365 is strategically significant. Enterprises using Microsoft 365 can now register Glean as an agent within the Agent 365 registry, deploy it to specific groups, and surface Glean’s cross-system search context inside Word, Outlook, and Teams. This means Glean and Microsoft Copilot are not necessarily competing in a winner-take-all sense, and many enterprises are running both.

For organizations building AI applications internally, Glean’s multi-model support (covering Amazon Bedrock, Azure OpenAI, and Google Vertex) provides flexibility that neither Microsoft nor Salesforce currently matches. Teams can choose different underlying models for different agents based on cost, performance, or compliance requirements.

Weaknesses and Honest Limitations

Microsoft Copilot Limitations

The core constraint is ecosystem lock-in. Microsoft 365 Copilot cannot natively search Salesforce, Slack, Confluence, Jira, or any system outside the Microsoft Graph without additional connector work. Only 6% of organizations that piloted Copilot moved to broader deployment, according to Gartner, pointing to real gaps between expectations and day-to-day utility in mixed-stack environments. As of early 2026, only 15 million users had purchased full Copilot licenses out of 450 million Microsoft 365 subscribers, a 3.3% conversion rate that suggests adoption has been harder than Microsoft’s marketing suggested.

Copilot’s licensing structure is also layered and complex. Maximizing agentic capabilities requires a combination of Microsoft 365 Copilot licenses, Copilot Studio message credits, Power Platform licenses, and sometimes Dynamics add-ons. For organizations without dedicated Microsoft licensing expertise, the total cost can be significantly higher than the advertised per-seat price.

Agentforce Limitations

Data quality is Agentforce’s single largest dependency. Agents pull from CRM records to answer questions and take actions. If the underlying Salesforce data is stale, incomplete, or inconsistent, agents confidently surface wrong answers. 77% of B2B deployments report failures tied to data quality issues, which makes any Agentforce initiative also a data hygiene project.

The 20-agent limit per organization remains a constraint for large enterprises, and latency concerns persist because Agentforce relies on external LLM calls that add response time. The pricing complexity, now spanning three concurrent models, creates budget unpredictability. Salesforce set an ambitious target of deploying one billion AI agents by 2025, but by mid-2025 had signed only about 8,000 deals, suggesting the market adoption curve is steeper than initial projections.

Glean Limitations

Glean’s architecture is optimized for search and knowledge retrieval, not CRM execution. Its Salesforce integration is a search connector, meaning it can surface Salesforce records in search results but cannot answer pipeline analytics questions like “what is our forecast gap this quarter?” or trigger Salesforce actions the way Agentforce can natively. For regulated industries, Glean’s cloud-only architecture has historically been a barrier, though the Azure single-tenant deployment option released in 2025 addresses some of these concerns.

Glean’s pricing opacity is a practical procurement problem. Without public pricing and with significant variation based on seat count, usage, cloud hosting configuration, and implementation scope, finance teams cannot get a reliable total cost estimate without going deep into a sales cycle. The fully loaded cost for large deployments often surprises buyers who anchored on the base per-user estimate.

Which Organizations Should Choose Which Platform

Choose Microsoft Agent 365 and Copilot when:

Your organization runs primarily on Microsoft 365, Teams, and SharePoint, and most knowledge work happens inside Microsoft apps
You need a centralized governance layer for AI agents across the enterprise, including third-party and locally running agents
Compliance and data residency requirements already commit you to Microsoft’s infrastructure
You are already at or moving toward E5 licensing and want to include agent governance without a separate budget line

Choose Salesforce Agentforce when:

Salesforce is your system of record for customer data, pipeline, cases, and service operations
Your primary AI use case is autonomous lead qualification, case routing, or quote generation inside the CRM context
Your CRM data is clean and well-governed, and you have the operational discipline to maintain it
Your sales and service teams already live in Salesforce and you want AI to work within that workflow rather than adding a new interface

Choose Glean when:

Your organization runs a mixed stack with significant Slack, Confluence, Jira, GitHub, or Google Workspace alongside Microsoft tools
The core problem is that employees cannot find information spread across dozens of systems
You want multi-model flexibility and the ability to choose different LLMs for different agents based on performance or cost
You need enterprise search context inside Microsoft 365 apps, which you can achieve through Glean’s Agent 365 integration

Consider using more than one:

The Glean and Microsoft partnership makes it reasonable for many enterprises to run both. Glean handles cross-system knowledge retrieval and is registered in Agent 365 for governance, while Microsoft 365 Copilot handles document creation and communication drafting in its native apps. Agentforce and Microsoft Copilot can similarly coexist when customer-facing CRM processes run on Agentforce and employee productivity runs on Copilot.

Enterprise AI Adoption Context

The enterprise AI agent market is growing fast but adoption is uneven. Research on Fortune 500 shows that most enterprises are still in pilot or early deployment phases. The challenges most commonly cited are data quality, change management, unclear ROI metrics, and governance gaps, not a shortage of capable technology.

Agentforce’s 330% ARR growth is real, but the low penetration rate within Salesforce’s existing customer base suggests that buying a license and actually deploying agents at scale are two different milestones. Microsoft Copilot’s 3.3% conversion rate from Microsoft 365 subscribers to paid Copilot licenses tells a similar story. Glean’s doubling of ARR to $200 million in nine months indicates that enterprise search and knowledge management remain a simpler first use case to actually deploy and see results from.

For most enterprises, the question is not which of these three platforms wins the AI agent race. It is which one solves the most immediate, well-defined problem in your organization’s existing stack, and whether you have the data quality and change management infrastructure to support autonomous agent workflows at all.

Frequently Asked Questions

What is Microsoft Agent 365, and how is it different from Microsoft 365 Copilot?

Microsoft Agent 365 is a governance and control plane for managing AI agents across an organization. It lets IT and security teams register, monitor, govern, and secure agents from Microsoft, third-party vendors, and internal developers, including discovering shadow AI running locally on Windows devices. Microsoft 365 Copilot is a separate product, the AI assistant embedded in Outlook, Teams, Word, and Excel. Agent 365 manages the fleet; Copilot does the day-to-day productivity work. Both are included in the Microsoft 365 E7 Frontier Suite at $99/user/month.

Can Agentforce replace Microsoft Copilot for enterprise employees?

Not practically. Agentforce is a CRM-native platform designed to automate customer-facing workflows inside Salesforce. Microsoft Copilot is a productivity assistant built for document creation, email, and meeting summaries inside Microsoft 365. They solve different problems. An organization might use Agentforce to automate lead qualification in Salesforce while using Copilot to draft emails and summarize meetings in Outlook and Teams. Swapping one for the other would require rebuilding significant functionality from scratch in an unfamiliar environment.

Does Glean compete with Microsoft 365 Copilot or work alongside it?

Both. Glean competes with Copilot for enterprise AI search and knowledge management budgets, especially for organizations running mixed stacks where Copilot’s Microsoft-only search is insufficient. At the same time, Glean became a launch partner for Microsoft Agent 365 in November 2025, integrating with Word, Outlook, and Teams so that Glean’s cross-system context surfaces inside Microsoft apps. For enterprises that need both deep knowledge retrieval and Microsoft ecosystem productivity tools, running both is a supported and increasingly common configuration.

What is Agentforce’s biggest limitation for enterprise buyers?

Data quality is the most cited blocker. Agentforce agents pull from Salesforce CRM records. If those records are incomplete, stale, or inconsistently structured, agents produce wrong answers with confidence. Agentforce review analysis found that 77% of B2B deployments report failures tied to data quality. Any Agentforce implementation is simultaneously a CRM data governance project, which adds significant scope, cost, and timeline to what looks like an AI deployment on paper.

Is Glean worth the cost for a mid-sized enterprise?

The answer depends heavily on how distributed your knowledge base is. For organizations running a relatively contained stack, primarily Microsoft 365 or primarily Google Workspace, Copilot or a Google Workspace AI add-on may be sufficient and significantly cheaper. Glean’s value proposition is strongest when employees regularly waste time searching across Slack, Confluence, Jira, GitHub, and multiple other systems for information that no single tool can surface. Fully loaded Glean costs for large deployments can reach $350,000-$480,000 per year, so the ROI calculation needs a clear baseline for time lost to knowledge fragmentation.

How does Agentforce pricing work in practice?

As of 2025, Salesforce offers three concurrent pricing models for Agentforce. Per-user licenses start at $125/user/month for Sales, Service, and Field Service. Flex Credits charge $0.10 per action, sold in packages of 100,000 credits for $500. The original $2/conversation rate still applies to some contract types. For enterprise commitments, Salesforce offers pre-commit discounts. The Flex Credits model introduced in May 2025 addressed some unpredictability, but the coexistence of multiple pricing models makes budget planning difficult without detailed contract review.

What does it actually cost to deploy Microsoft 365 Copilot at scale?

The visible cost is the $30/user/month Copilot add-on on top of your existing Microsoft 365 Enterprise license. But organizations aiming to use agentic capabilities will also need Copilot Studio message credits for custom agents, Power Platform licenses for workflow automation, and sometimes Dynamics add-ons for specific vertical use cases. A 1,500-seat Copilot deployment on top of E3 licenses adds approximately $540,000 per year in Copilot licensing alone, before implementation services, Copilot Studio consumption, and ongoing administration are factored in.

Which platform is best for a company that uses both Microsoft 365 and Salesforce?

Organizations running both platforms typically use Agentforce for customer-facing CRM automation, where Salesforce is the system of record, and Microsoft 365 Copilot for internal employee productivity inside Teams, Outlook, and Office apps. Both products register and appear within Agent 365 for centralized governance. The only gap this combination leaves is cross-system knowledge search, which is where Glean’s integration with Agent 365 makes it worth evaluating as a third layer, particularly if the organization also runs significant knowledge in Confluence, Slack, or GitHub.

The Bottom Line

Microsoft Agent 365 is the enterprise governance answer to a real problem: AI agents are proliferating across organizations faster than IT can track them. As a control plane, it fills a gap that neither Agentforce nor Glean address directly. For Microsoft-committed enterprises moving toward E7, it is an important capability included in the bundle rather than a separate buying decision.

Salesforce Agentforce is the strongest option for CRM-centric automation. No other platform offers the same depth of native access to Salesforce data and processes. The adoption and data quality challenges are real, but for organizations with clean CRM data and Salesforce-native workflows, Agentforce can deliver autonomous revenue operations that no competitor matches out of the box.

Glean is the platform for organizations that genuinely live across multiple ecosystems and need AI that works across all of them rather than being excellent within only one. Its integration with Microsoft Agent 365 removes the either-or choice for many enterprises, making it a complement to Copilot rather than a replacement.

The question for your organization is not which platform sounds most impressive in a demo. It is where your data actually lives, what processes you want AI to handle autonomously, and whether your data governance is ready for autonomous agents to act on it.
