The advertised Thunderbird Migration from EWS to Graph DOES NOT WORK!

Thunderbird Parole și autentificări

I have read the topic "Microsoft EWS to Graph Migration October 2026". I have followed the instructions meticulously MULTIPLE TIMES. Unfortunately for me, it DOES NOT WORK!! After deleting the EWS account, I proceed to create the new Graph account, but it fails (has failed) EACH AND EVERY TIME I've tried it. I finally had to give up, and restore/re-install/setup the Thunderbird EWS version. The failure reported on each failure was an "authentication failure".

My OS is macOS Tahoe 26.7.1; My Thunderbird version is 158.0. This is distressing! If there is an issue, I would expect T'bird to belay the update until the issues were fixed. If there is a "trick" required, I would appreciate someone sharing it with me. I'm aware that the causes of these issues is "Microsoft Incompetence", but AFAIK incompetence is not "contagious" - I don't understand T'bird/Mozilla releasing a fix with detailed procedures without testing.

EDIT: One other piece of information that may or may not be useful. The article "Microsoft EWS to Graph Migration October 2026" mentions a "Microsoft 365/Exchange Online email account". My account is an "Exchange Server" account; the Exchange server is hosted by Microsoft.

Thanks for any advice.

Best Regards, ~JM

If you're using Exchange Server, then you should continue using EWS. I was not aware that Microsoft provided hosted Exchange Server accounts, but the Graph migration applies *only* to users of Microsoft 365 and Exchange Online accounts and Exchange Server does not support the Graph protocol at all.
