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

    According to MS this is not related to any planned elimination of authentication protocols, etc. If you are using app passwords you should be all set, but most are still seeing the problem. When you reset your network or DNS, you get connected to a new server, and it seems some servers are having the problems and some aren't. When the problem happens for me, I have to bounce the network once or twice and it will go away as I get a new server that has the fixes applied.

    The best way to go is modern authentication, but not all apps support that, at least not for outlook.com addresses.

    Bounce your network connection (let it stay down for 30 seconds) and see if you can reconnect, may have to try it a couple times.

    The reason it works if you keep hitting OK is eventually it tries another server (as you've likely gotten temporarily blocked from the server you were retrying to repeatedly, a security feature) and happens to get one that works that next time.

    I have a iPhone XR 14 Pro Max & an iPad Air Software version 12,5,7. Both of these devices were asking for passwords over & over & not accepting. I have deleted the exchange accounts & now neither of these devices will accept me adding back in the accounts. I pay for Microsoft 365 Family. Please help as this is debilitating.

    Agreed. Numerous work arounds in this thread. None lasted permanently. Only MS can fix this for all of us.

    Yeah, not resolved, I mean, for two days, the service worked alright. Now the problem is alive and kicking.
