Claude offers in-app experiences in Excel, PowerPoint, Word, and Outlook, plus a separately configured connector for searching and analyzing work content. Microsoft describes Copilot across Word, Excel, PowerPoint, Outlook, Teams, and other Microsoft 365 apps; Copilot Chat is distinct from the paid Microsoft 365 Copilot add-on. The right fit depends on your apps, tenant policies, and whether you need to find information, edit files, or take actions.
What does each assistant do in Microsoft 365?
Anthropic describes Claude for Microsoft 365 as working within Excel, PowerPoint, Word, and Outlook. Its examples include spreadsheet modeling, creating slides, making tracked edits and comments in Word, and helping with inbox and calendar tasks. Anthropic marks the Outlook experience Beta, so check current availability before depending on it in a production workflow.

Claude: a separate Microsoft 365 connector
Claude’s Microsoft 365 connector can search and analyze content in SharePoint, OneDrive, Outlook, and Teams. Anthropic says it requires a work Microsoft 365 account associated with a Microsoft Entra tenant; personal Microsoft accounts, including consumer Outlook accounts, are not supported. An organization administrator must configure access. The connector’s availability is listed for Claude Free, Pro, Max, Team, and Enterprise plans, but that listing does not establish a complete price or enterprise-cost comparison. See Anthropic’s connector documentation.

Microsoft: Copilot Chat and work-data grounding
Microsoft says Copilot Chat can ground responses in work data according to the user’s existing access permissions: it cannot include work data the user is not permitted to access. The scope and capabilities depend on whether the user has a Microsoft 365 Copilot add-on. Microsoft’s pages distinguish the chat experience from the add-on; the name “Copilot” alone does not identify which one is available. Read how Copilot Chat works in Microsoft 365 apps and how grounding works with a work or school account.
Can either assistant change files or send messages?
Searching or analyzing information is different from taking an action. Anthropic says Claude’s connector can perform listed email, calendar, file, and Teams actions when the relevant write tools are enabled. Do not assume those tools are on by default: an administrator’s configuration determines what is available. Anthropic also describes edits as reviewable and actions as waiting for user approval on its product page. For any workflow that changes data or communicates externally, ask IT which tools are enabled and what approval steps apply.
Microsoft’s cited pages explain Copilot grounding in relation to user permissions, but do not provide a complete feature-by-feature comparison of action controls. Verify the exact workflow and approval behavior with your administrator rather than inferring it from general product descriptions.
Which assistant fits common workplace tasks?
| Work need | Claude | Microsoft Copilot | What to check |
|---|---|---|---|
| Work mainly inside Office files | Anthropic lists Excel, PowerPoint, Word, and Outlook experiences. | Microsoft lists Word, Excel, PowerPoint, Outlook, Teams, and other Microsoft 365 surfaces. | Confirm the exact app features and availability for your plan and platform. |
| Find material across company repositories | The connector names SharePoint, OneDrive, Outlook, and Teams. | Copilot Chat grounding respects the user’s work-data permissions; scope depends on licensing. | Ask IT which sources are connected and what your account can access. |
| Turn information into work across apps | Anthropic gives examples such as turning an email into a document, model, and presentation while retaining context. | Microsoft describes Copilot across multiple Microsoft 365 apps, but the cited pages do not establish an equivalent end-to-end task comparison. | Treat these as vendor-described workflows, then check the actual steps and access in your tenant. |
| Take actions, such as handling email or calendar items | Connector write actions depend on enabled tools and organizational setup. | The cited documentation does not establish a complete action-control comparison. | Verify enabled actions, approvals, and review controls before relying on automation. |
How do the licensing and setup differ?
Microsoft says Copilot Chat is available to businesses with a Microsoft 365 subscription at no extra cost, while capabilities are narrower without the Microsoft 365 Copilot add-on. This does not establish the price of the add-on or a complete like-for-like cost comparison. Anthropic lists the Claude plans on which its connector is available, but the connector page does not provide a complete enterprise price comparison. Check current regional pricing, included usage, add-on requirements, and procurement terms directly with each provider and your organization.

For Microsoft, confirm the specific work or school account and Copilot license, as well as the tenant’s policies. Availability and licensing can vary by tenant, plan, and region.
Independent reader supportYour contribution helps us test, update, and keep practical guides available for everyone.How to choose for your workplace
- Name the task. Decide whether you need help within a particular Office app, cross-repository search, document creation, or an action such as sending or changing something.
- Check the data boundary. Ask IT which repositories each assistant can access, how existing permissions apply, and whether the relevant connectors are enabled.
- Verify the license and feature status. Distinguish Copilot Chat from the Microsoft 365 Copilot add-on, and check Claude’s plan and the current status of features marked Beta.
- Test the actual workflow under your organization’s rules. Confirm review and approval steps before using an assistant for changes or communications.
The official materials establish overlapping Microsoft 365 support, but not a controlled comparison of accuracy, productivity, or return on investment. A categorical winner is not supported by these product descriptions. Choose based on the specific app coverage, work-data access, tenant setup, and action controls your organization permits.
