Thunderbird:Exchange
Warning: Exchange support in Thunderbird is new. We recommend backing up your Thunderbird profile before using it.Our Exchange implementation is via the EWS API (Exchange Web Services), currently limited to email. First enabled in version 141, version 145 is almost feature complete for email, with some items still in progress listed below.
Calendar and address book will follow at a later date. Also in the future is Exchange via Graph API, so please do not file bug reports for these items at this time.
Setup
When creating a new account using classic account creation, choose the "Exchange Web Services" option. Or if using the new Account Hub, when providing an exchange email address, "Exchange" should be automatically detected. If exchange is not detected, choose the first "Exchange" option. For additional basic information about setup see the Exchange knowledge base article.
