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

Using classic Outlook for Windows in business environments
Locked Question. This question was migrated from the Microsoft Support Community. You can vote on whether it's helpful, but you can't add comments or replies or follow the question.
I've never used IMAP with outlook but I know many others it can't, it just stores it in a local file. But maybe MS has implemented it.
IMAP works better but not acceptable to me because I need contacts and calendar sync as well - I figure it's the same for most people.
IMAP can sync contacts and calendar - well at least it could a week ago.
Yeah I've done that a few times, didn't seem to help any.
This is just for my phone, my windows PCs run outlook client and it has been fine all along (it uses MAPI over HTTPS).
Regardless of the terms, I've seen it and it blows. I am not looking forward to when it is the only option.
"New Outlook" has new terms and condition, and by using it, you agree to send and share all your emails and 3rd party account data with Microsoft. So think and read that before you opt to use it. "New Outlook" on Win11 is a PWA. For MS accounts, it probably doesn't matter, BUT if you access any non-MS accounts, it means MS cloud will be the middle man accessing your non-MS account data and refurnishing it to you on your screen. It's very very different than the Outlook desktop which is a local client. "New Outlook" is a cloud client.
