It has 178 installs sharing analytics, needs the vendor's cloud and was last updated October 26, 2026. Microsoft 365 - Mail is an integration that reads and sends Microsoft 365 email from Home Assistant. It adds sensors for mail in a chosen folder and a notifier for sending messages, and it relies on Microsoft's cloud. The sensors can be filtered by sender, attachments, importance, unread state, and text in the subject or body. Options also cover showing attachment names, saving attachments, and outputting the body as HTML. Actions can schedule or disable an automatic reply, and a shared mailbox can be used. Setup is done in the UI with a client ID and client secret. Automatic summary of the README and code of RogerSelwyn/MS365-Mail. Something wrong, or are you the maintainer and want your own text here?
