This integration is slowly moving towards EOL. I have already created integrations which will replace it - MS365-Calendar/Mail/Teams/ToDo, these can be used now using HACS Custom. When these are available on HACS Default I will then stop work on O365-HomeAssistant.
Many will have seen a warning in the logs - Detected that custom integration 'o365' uses 'async_config_entry_first_refresh', which is only supported for coordinators with a config entry and will stop working in Home Assistant 2025.11
- this further forces the EOL due to a change in HA Core, which means that the integration will cease to work after the 2025.11 HA release without really significant re-work. Because this integration is setup via YAML, it does not have a config_entry
, the replacements listed above do.

This is a fork of the original integration by @PTST which has now been archived.
This integration enables:
This project would not be possible without the wonderful python-o365 project.
I work on this integration because I like things to work well for myself and others. Whilst I have now made significant changes to the integration, it would not be as it stands today without the major work to create it put in by @PTST. Please don't feel you are obligated to donate, but of course it is appreciated.

Nice video from fixtse showing how to install the O365 integration to Home Assistant. Also providing some Lovelace cards for displaying content from O365 - O365 Card for Home Assistant
