My University has just announced (with 2 weeks notice!) that support for Basic Authentication for Microsoft Exchange will be ended on 15 Jun. Thereafter all email clients must use MS Graph API. Will Thunderbird continue to work? Or will I be forced to change to Outlook (after many years with TB)?

Chosen solution

As far as I know, Thunderbird doesn't yet support MS Graph. Support for MS Graph will be a desirable inclusion to Thunderbird, and hopefully the development community will pick up on it and create a solution for it, if they aren't already working on it. Until that is done, Thunderbird won't be able to communicate with MS 365 email servers. I can't say how long it will take to update Thunderbird for MS Graph support.

Stans, thanks very much for a clear and thorough answer, although not the one I had hoped for. I have Thunderbird on four computers, all of which will stop working on 15 Jun. So it is goodbye Thunderbird, I am sorry to say.

Although MS says that they will support existing logins until October, if many organizations are setting earlier deadlines--as mine is--Thunderbird's user base may erode rather quickly.

Yeah. I hope Microsoft will play nice and co-operate with third-party client support when they retire EWS. MS really wants you to use its own clients.
