Outlook Calendar

Connect Outlook Calendar to check availability and manage Microsoft 365 meetings.

What it can do

• List calendars and read events.
• Check attendee availability.
• Create, update, cancel, or delete events.
• Accept, decline, or tentatively accept invitations.

Setup and security

• You sign in with your own Microsoft account. Assistant can reach only the calendars that account can see.
• Tools that change data ask for approval before they run. The Approval column under Supported tools shows each tool's setting.
• Updating an event's attendees replaces the whole attendee list. Canceling an event notifies attendees; deleting it does not.
• Your Microsoft 365 administrator may need to approve Nomic before you can finish signing in.
• Outlook Calendar and Outlook Mail are separate sign-ins. Both are separate from the Outlook integration under Settings → Integrations.

To connect, see Add an MCP server.

Example requests

• "What's on my calendar for the week of the owner walkthrough?"
• "Find a time next week when the architect, the superintendent, and I are all free for an hour."
• "Create a punch walk on Friday at 9am with the subcontractor leads."
• "Cancel Thursday's OAC meeting and let the attendees know."
