# Microsoft 365

[Connectors](https://lumman.co/mcp) / [Multi Calendar](https://lumman.co/mcp/multi-calendar)

Work and school calendars on Microsoft 365 connect to Multi Calendar with Microsoft sign-in, once your organisation allows it.

For calendars Microsoft hosts in Exchange Online - not your organisation's own Exchange server.

## Add it to Claude

1. [Add to Claude](https://claude.ai/directory/connectors/lumman-multi-calendar) - Opens claude.ai - press Connect there.
2. Sign in, choose Outlook.com or Microsoft 365 and allow access at Microsoft in the window Claude opens. That adds your calendar and approves Claude in one step.
3. Ask Claude about your week

## Limits

- If Microsoft says your organisation has to approve Lumman first, Lumman shows the address where your administrator approves it. Once they have, connect the calendar again.
- An event can show you as out of office, but Outlook makes no focus time.
