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
Pierre

Continues to request new sign in. No new emails being received. Generally, the sign in takes and new emails start to arrive, but unless I check the 9Folders app to see the authentication error or the sign-in request, I don't know I'm getting new emails. Really, really hope that MS is making some progress here. 24 days and counting.
Have you tried removing and re-adding your account/s? It worked for me.
Another authentication error just now. 9Folders email client. Exchange Activesync.
Thank you for your help bringing attention to this matter, Pierre. You may not have noticed, but Gabriel Bratton, another Microsoft Agent on this Answers forum, has been kindly active here with us working as a liaison with the Outlook Team, and posting updates periodically on your thread. That said, I agree with you that the Support incident report should not be marked RESOLVED.
Hi everyone,
I started this thread 25. jan 2024 😎
In this thread I found Microsoft Agent Kathy A.: Outlook.com App Passwords not working on iPhone - Microsoft Community
Today I did this text in that thread to Kathy A.

Hi Kathy A.
Thanks for looking into this problem. It is incredibly much appreciated.
You are saying:
"Yes, this is still ongoing known issue with the email set up of Outlook.com/Hotmail.com on any mailbox. However, app password is the workaround for this issue, and we would suggest you try to generate another app password for your Outlook on Apple Mail app."
But we still get the "windows" password popup.
I'm using Win11, Outlook 2016 plus and my Hotmail account. Everything is "up to date"!
Outlook 2016 doesn't accept password or app password - Microsoft Community
Outlook and other apps are unable to connect to Outlook.com - Microsoft Support
The authentication problem occurred suddenly - so something has changed at Microsoft around this date (25. jan. 2024)
Kind Regards
Pierre

We all in this thread are not gonna solve anything on this problem - if Microsoft are not "going back" to what the system setup was before 25. jan 2024.
Even not with a nice reg. fix ...
So - do YOU know anyone inside Microsoft?
