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

    02/11/2024 ~2PM PST Works intermittently.

    After several days couldn't get it connect even with new app password, today it accepted new app password, updated all folders, but less than an hour later it prompted for password again.

    You need to enable 2FA and use modern authentication, which Outlook 2016 should support by default now. App password doesn't solve the current issue (though it should work fine once this is resolved, at least until they totally do away with app passwords).

    For me, my phone has prompted me a few times yesterday and today but I just refresh my inbox and it goes away and mails send and receive fine. So still not fixed, but better than a few days ago. Why it was fine for a couple days and now backtracked, who knows.
