Right now the best estimate is around the time of next year's ESR, so some time around the end of June 2026!

Exchange/Microsoft365 account support built into Thunderbird now!

Thunderbird users have asked us for this for years and now it is here. Enjoy.

For nerds: the architecture built for this opens the door for JMAP support.
