Verification error trying to open Exchange email account on Thunderbird
Up till yesterday Thunderbird (release 99.10) was working fine on my Exchange account. Since this morning Thunderbird was claiming my password was not correct. However I can use this same password on my iPhone and on Outlook. I decided to change he password. The new password again works on the iPhone and Outlook but not in Thunderbird.
Today I upgrade Thunderbird to the latest version 102.0 and also reverted to version 98 but same problem.
I deleted the account and tried to add it back again and I get a verification error:
Configuration could not be verified. If you username and password are correct, it's likely that the server administrator disabled the selected configuration for your account. Try setting another protocol.

Same problem for me, however I'm using Office365 rather than Exchange. No problems with my password but I changed it anyway, can log into the https://outlook.office365.com just fine but not through TB. Also on 99.10 and then manually upgraded to 10.2, didn't try a downgrade though.
Hi, I would be happy to hear if you find a solution? I am now stuck using Outlook which is painful. Gideon
After three days the problem resolved itself on it's own.
