I have this problem - Outlook 2016 doesn't accept password or app password - and i think it is a growing World wide Microsoft problem :-(
See also here: https://www.reddit.com/r/Outlook/comments/19dx64p/outlook_2013_windows_10_suddenly_not_accepting/Outlook gives me this: (startede yesterday)
I have 2 PC's with HOTMAIL accounts in Outlook 2016 ...
They both have this error.
I do get mails ... but I can´t send mails. Yesterday it did work for 1-2 hours ... but right now the error is there all the time :-(
Please help me.
Thanks in advance

2024-03-19T15:34:43+00:00 Totally agree. Why some work and others don't, all identical is a bit frustrating. BTW, my 9Folders changes this past Sunday (yes, finally go to it!) seems to be working for now. Will report back if not.

2024-03-19T05:20:05+00:00 Just got an authentication error for my Hotmail account using all the recommended settings in the latest version of Thunderbird 115.8.1
- IMAP with server outlook.office365.com and port 993
- OAuth2 (which worked for about 2 weeks after switching from basic/normal authentication on March 5, with no major issues until now)
Time stamps are PDT.
I am also again experiencing extreme slowness synchronizing (opening and closing folders, downloading and marking messages). This again seems to be the same extreme throttling issue I was experiencing before switching over from basic authentication which was alleged would be resolved using OAuth2.
Gmail account works flawlessly using OAuth2.Frankly, this authentication problem is outrageous, and clearly systemic regardless of what method is being used.
