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

Incident has just been updated to acknowledge the problem is still occurring for some and that the Outlook.com team continues to look into the issue.
Ok, can also confirm that I was able to re-add my @live.com,au address to my Gmail app as Exchange. Won't go as far to say it's resolved, will monitor and update of any changes
Down all day today. Switched to mobile data and it reconnected, back to wifi and it stayed connected. There are obviously still servers at MS that haven't gotten the fix, and it is hit or miss which one you get assigned to.
similar pattern for me since yesterday. outlook 2019 macOS desktop, affected accounts: hotmail, still getting password requests few times a day but when I hit refresh instead of entering password, it was able to connect again. Before this issue, maybe I only got password pop-up couple times a year. I'd say it's improving but far from "resolved".
for reference, I've been running Thunderbird since early this week as a backup for outlook. Thunderbird doesn't seem to be impacted by this issue. I only got password request maybe once on Thunderbird throughout the week. No issue with Apple mail on Iphone.
I have a separate but related problem
Until this Outlook 2016 problem started, I was successfully holding both outlook.com and gmail mail accounts in my local Outlook 2021 system on Windows 11. at the same time as the Outlook 2016 problem started, the system told me to renter my outlook.com account details, but it would not accept the login details (which were correct). I therefore deleted the outlook.com account from my local Outlook 2021 system, but now when I add it back again, the login details are accepted, but I cannot access any email or calendars on either my outlook.com account or my Gmail accounts. I get the error 0x80040111 and the message " The server is unavailable"
As soon as I delete the outlook.com account, everything starts to work again.
Has anyone else seen this problem?
