This store suits Microsoft 365 Copilot users looking for agents across the listed types and installation channels. Its plans are listed for organizations with up to 300 users.

Microsoft 365 Copilot Agent Store is a catalogue and delivery point for agents that work across Microsoft 365. It is aimed at organisations already using Microsoft’s productivity applications and needing both ready-made and build-your-own options. The broad reach is compelling, but paid annual subscriptions and a 300-user limit make the choice of plan consequential.

Overview

The store covers several agent approaches, from ready-to-use tools to declarative and custom-engine agents, Copilot Studio, SharePoint agents and connectors. Publishing access is reviewed, which gives organisations a screened route for distributing agents rather than an entirely open directory. Microsoft, founded in 1975 and headquartered in Redmond, Washington, supports the service on Android, iOS, macOS, web and Windows.

This is most useful when agents need to sit inside familiar Microsoft work. It is less compelling for a team seeking a platform-neutral marketplace or a free way to experiment, because access is tied to paid subscriptions billed yearly.

Key features

Agent formats for different jobs

Ready-to-use agents suit teams that want an existing starting point. Declarative and custom-engine options, along with Copilot Studio, are better suited to organisations shaping behaviour around their own processes. SharePoint agents and connectors address content and connected-system scenarios. The range is a practical strength for mixed requirements, although it also puts the burden on buyers to choose the right format rather than assuming every agent serves the same purpose.

Install where work happens

Agents can be installed through the Microsoft 365 Copilot Agent Store and Microsoft Marketplace, or surfaced in Microsoft Teams, Outlook, Word, Excel and PowerPoint. That distribution is valuable for teams that want agent access in the applications they already use, reducing the case for a separate destination. Reviewed publishing access adds a measure of control for organisations managing what reaches users.

Pricing

All listed plans are paid yearly subscriptions and renew automatically. Microsoft 365 Copilot Business costs $21.00 per user per month, billed paid yearly, for up to 300 users. It is the entry point for organisations that want Copilot agents without the additional storage allocation attached to the Standard and Premium tiers.

Microsoft 365 Business Standard with Copilot costs $23.50 per user per month, billed paid yearly, and also supports up to 300 users. It adds 1 TB of cloud storage per user, making the modest increase over Business easier to justify for teams that need per-user storage as part of the package.

Microsoft 365 Business Premium with Copilot costs $32.00 per user per month, billed paid yearly, for up to 300 users and includes 1 TB of cloud storage per user. The higher price is aimed at organisations that need the Premium tier’s broader package rather than simply access to the store. None of these plans is a small-team free tier, and the annual commitment and automatic renewal should be accounted for in budgeting.

Platforms

Support spans Android, iOS, macOS, web and Windows. The installation routes extend through Teams, Outlook, Word, Excel, PowerPoint, Microsoft Marketplace and the Agent Store, so the strongest fit is a Microsoft 365 environment spanning desktop, browser and mobile users.

Who it's for

Choose it if your organisation already relies on Microsoft 365 and wants a governed place to find, build or connect agents across its productivity apps. The Business plan fits teams focused on agent access; Standard is more suitable when 1 TB of storage per user matters; Premium is for organisations that specifically need that higher package. It is a poor fit for individuals seeking a free trial-style entry point, or for teams outside Microsoft’s application ecosystem.

Pros and cons

• Pros: multiple agent types support both ready-made adoption and more tailored projects.
• Pros: installation in Teams, Outlook, Word, Excel and PowerPoint keeps agents close to daily work.
• Pros: reviewed publishing access provides a more controlled route for organisational deployment.
• Cons: every listed plan is a paid annual subscription with automatic renewal.
• Cons: plans cap deployment at 300 users, limiting larger organisations.
• Cons: the entry plan does not include the 1 TB-per-user storage specified for Standard and Premium.

Verdict

Microsoft 365 Copilot Agent Store is a strong choice for organisations committed to Microsoft 365 that need varied agent types, reviewed publishing and installation inside core productivity apps.
