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

Outlook 2021 on W10 should not have any problems. Do you have 2FA enabled on your account and using modern auth (not a password or app password) in Outlook?
As they say, the grass is always greener. I moved my email domain to Outlook after many problems with the G one. This is the first time in 10 years that there has been an issue, and at that it is only on my phone, my PCs using Outlook and modern auth have had 0 issues.
@Microsoft:
Your information here is wrong: https://support.microsoft.com/en-us/office/outlook-and-other-apps-are-unable-to-connect-to-outlook-com-f4202ebf-89c6-4a8a-bec3-3d60cf7deaef Issue is still NOT SOLVED !!!
Same as before your "implemented service changes": Password prompts even with Outlook 2019 !!!
Agree 100%

During the first week of this issue since Jan. 23 to Jan. 30 we started moving critical services that were registered to our Outlook/Hotmail/Live accounts to another major competitor (not hard to guess who that might be-G). At this point we have completed this process and will not be returning to Microsoft's e-mail services. It's simply too unreliable. Everything works perfectly fine with the other provider in all e-mail clients on all devices, Microsoft and 3rd party, new and old.
