# Office 365

> Office 365 is a Marketplace integration for Home Assistant. It has 109 installs sharing analytics, needs the vendor's cloud and was last updated November 12, 2025.

Office 365 is a Home Assistant integration that connects to Microsoft's cloud for calendars, mail, Teams and tasks. It provides calendar, notifier, sensor and to-do platforms, covering reading and creating calendar events and to-do tasks. Two sensor types read emails from an inbox, and a notify service sends email. It can also report Teams presence and the latest Teams chat message, though not for personal accounts, and it can set an out-of-office auto reply. This is a fork of an archived original project, and it is now deprecated: development has stopped except for changes that support migration to the separate MS365 integrations. It is configured through YAML, and it can show a repair notice about a deprecated configuration method.
