Outlook MCP and Claude skills

Search your Outlook inbox and calendar for unread mail, flagged messages, threads waiting on you and today's meetings, and post a short triage list.

Connect Outlook to your agent (MCP)

  1. Microsoft 365 connector in Claude. Anthropic's connector searches Outlook mail and calendars along with SharePoint, OneDrive and Teams, on every Claude plan. It needs a work or school Microsoft account (personal outlook.com and hotmail.com accounts aren't supported), and a Microsoft Entra Global Administrator grants tenant consent once. Reading and searching are on by default; sending mail and changing events are write actions your admins turn on (docs). Connectors added in claude.ai also appear in Claude Code when you sign in with that account.
  2. Work IQ MCP server. Microsoft's own MCP server for Microsoft 365 data, mail and calendar included, is in preview (as of October 2026) and needs a tenant admin to set it up.
  3. Microsoft Graph with your own app. Register an app in Microsoft Entra ID with delegated Mail.Read, Calendars.Read and offline_access, allow public client flows, sign in once with the device code flow, and store MS_TENANT_ID, MS_CLIENT_ID and MS_REFRESH_TOKEN. This route also works for personal Outlook.com accounts through the consumers tenant.

Mail.ReadBasic is enough when a report needs only senders, subjects and dates, not message bodies. If you use application permissions for a shared mailbox, limit the app to that mailbox with RBAC for Applications in Exchange Online.

What agents do with Outlook

Agents read Outlook mail and calendars through Microsoft Graph. GET /me/mailFolders/inbox/messages takes OData filters such as $filter=isRead eq false and receivedDateTime ge 2026-10-16T00:00:00Z, $select to keep responses small and $search for keywords and senders. Messages carry subject, from, receivedDateTime, conversationId, importance, flag.flagStatus and inferenceClassification (focused or other), which separates the Focused inbox from the rest. GET /me/calendarView?startDateTime=...&endDateTime=... returns every occurrence of recurring meetings in a range, with attendees and their responses.

People schedule a morning triage of unread Focused mail, flagged messages past their due date, threads where someone has waited days for a reply, today's agenda with who is in each meeting, and invites still waiting for an answer.
