Okay, #Outlook, #MicrosoftOutlook, #Hotmail, whatever... isn't working correctly on #Thunderbird, #KMail, or #Vivaldi email clients. I haven't changed the settings. I'm starting to think it's #Microsoft messing with non-Microsoft email clients. I really need to dump my old Hotmail addresses, this is a complete pain.

in reply to Jeff • • •Hi! We've been seeing this, and there is a bug that is switching the authentication. (https://bugzilla.mozilla.org/show_bug.cgi?id=1875633) What has worked is going into Account Settings and switching from Normal Password to OAuth2 and going through the sign in process, confirming your identity, and authorizing Thunderbird. This seems to correct the behavior for most people who have done this. Please let us know if this works for you!

It seems to be working so far, but I'll keep an eye on the situation.
