Which Outlook server you can use depends first on your account. With a work or school account, use Microsoft's Work IQ or Claude's built-in Microsoft 365 connector, and expect your IT admin to approve it once. With a personal Outlook.com or Hotmail account, those do not work, so use a community server such as Softeria's, which signs you in with a code and needs no Azure setup. Microsoft's older Outlook Mail server only works inside Copilot Studio, and Microsoft says it is kept only for backward compatibility.
Good for
- People at work who want Claude or Copilot to search, summarize and draft replies in their company mailbox
- Outlook.com and Hotmail users who want an assistant to triage a personal inbox
- IT admins deciding which Outlook connection to approve for their tenant
- Developers wiring Outlook mail and calendar into Claude Code, Cursor or VS Code
- Windows and Mac users who would rather use the Outlook app already on their computer
Which Microsoft Outlook MCP server to use
On a work or school account, use Work IQ if your company has Copilot licenses, or Claude's Microsoft 365 connector if you use Claude, and ask IT to approve it. On a personal Outlook.com account, use Softeria's server, or mpalermiti's if you want a server built only for personal mail.

Questions
Does Microsoft have an official Outlook MCP server?
Yes, but Microsoft keeps its Outlook Mail MCP server in Copilot Studio only for backward compatibility and says not to use it in new projects. For new work Microsoft points to Work IQ, which covers Outlook mail along with the rest of Microsoft 365.
Can I connect a personal Outlook.com or Hotmail account?
Not to Work IQ or Claude's Microsoft 365 connector, which both need a work or school account. Use a community server instead. Softeria's works with personal accounts by default, and mpalermiti's is built only for them.
Do I need my IT admin to approve it?
For Work IQ and Claude's connector, yes. An administrator approves it once for the whole company, then everyone can sign in. A community server on a work account can hit the same approval screen if your company blocks users from approving apps themselves.
Which admin role can approve it?
Claude's connector needs a Microsoft Entra Global Administrator for the first approval. Work IQ accepts a Global Administrator, Privileged Role Administrator, Cloud Application Administrator or Application Administrator.
Does Work IQ need a Copilot license?
Microsoft's Work IQ admin guide lists a Microsoft 365 Copilot license for each user, on top of a base plan such as E3, E5 or Business Premium. Without those licenses, Claude's connector or a community server is the alternative.
Do I have to register an app in Azure?
Only for some community servers. ryaker's, mpalermiti's and Outlook Assistant need your own app registration, and personal-account users need a free Azure account to create one. Softeria's server has a built-in app, and Work IQ and Claude's connector need nothing from you.
Can the assistant send or delete my email?
Most servers can, if you give them permission. Claude's connector only reads and searches until your admins turn on write actions. Softeria, Outlook Assistant and mpalermiti's server each have a read-only setting, and ryaker's has none.
Can it use the Outlook app on my computer instead?
Yes. Outlook Classic MCP drives classic Outlook on Windows, and claude-outlook-mcp drives Outlook for Mac. They use the account Outlook is already signed into, so there is no app registration or admin approval. The new Outlook for Windows is not supported.
Why does Softeria's server keep asking me to sign in?
On personal accounts the sign-in expired about an hour after login with the default setting. Setting MS365_MCP_TENANT_ID=consumers fixed the refresh for the user who reported it.
