Can AI agents automate Microsoft Outlook?

Outlook mailbox data is broadly automatable through Microsoft Graph. Agents can read, draft, send, reply to, forward, move, categorize, and delete mail; manage calendars, events, contacts, folders, settings, and rules; synchronize changes; and subscribe to change notifications. The API works with personal and organization accounts and supports delegated and application access, but archive mailboxes are excluded and tenant permissions remain a material control. Outlook web add-ins and the first-party Power Automate connector add event and workflow paths across clients. Classic Outlook desktop automation remains available but is not compatible with the new Outlook for Windows. Opened https://github.com/microsoft/mcp on 2026-09-18: the official catalog lists Microsoft 365 Mail and Microsoft 365 Calendar remote servers and does not list a product-named Microsoft Outlook server. This record treats those Mail and Calendar entries as Microsoft 365 surfaces, not as an established Outlook-client first-party MCP; vendor documentation does not settle Outlook MCP ownership, so MCP remains unknown. The opened Graph mail API overview and Outlook add-ins overview do not document a product-specific official Outlook CLI. Zapier, Make, and n8n catalogs were not opened as Outlook connectors. Computer-use viability is unassessed; no probe artifact exists. https://learn.microsoft.com/en-us/microsoft-365/llms.txt and https://learn.microsoft.com/en-us/office/llms.txt returned HTTP 404 on 2026-09-18.
