About
Microsoft Calendar is an integration that brings Microsoft calendars into Home Assistant as calendar entities. It covers Microsoft 365 work or school accounts as well as personal Microsoft accounts, and each calendar, such as work, personal or shared, gets its own entity. A calendar entity is on while an event is active and off otherwise, and events can be browsed in the Home Assistant calendar view. Recurring events are expanded by Microsoft Graph, so no extra logic runs on the Home Assistant side. Sign-in goes through Microsoft's own page using the OAuth authorization code flow with PKCE, so no client secret is stored, and token refresh is handled automatically. Setup happens in the UI, with a choice between read-only and read-write access, and a built-in app registration is provided while a custom one can be used instead.

From the README
A custom Home Assistant integration that exposes your Microsoft / Outlook / Microsoft 365 calendars as native calendar entities. Each calendar becomes its own entity you can use in dashboards, automations, and scripts.
Authentication uses the OAuth 2.0 Authorization Code + PKCE flow — no client secret is stored anywhere.
- One calendar entity per Microsoft calendar (work, personal, shared)
- STATE_ON when an event is currently active; STATE_OFF otherwise
- Full event browsing in the Home Assistant calendar UI
- Recurring events automatically expanded by Microsoft Graph — no client-side logic needed
- Supports both Microsoft 365 (work/school) and personal Microsoft accounts
- Token refresh handled automatically; re-auth flow triggered when the refresh token expires
- No third-party Python SDK — only standard HTTPS calls to Microsoft Graph
