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

    I'm also having the same issue in Outlook 2013, Thunderbird 115.7.0, and the default mail app on Lineage OS 8.1.0. Using Oauth2 in Thunderbird has fixed the issue for now, but on phone I have to attempt to login about 6 times before it works.

    Same issue on Mailbird. Cant Authenticate Outlook.com credentials. Mailbird support states many are having this problem and that it is a Microsoft Issue.

    My name is Dasha, and I'm reaching out to you since you recently contacted us in relation to severe problems which have impacted one or more of your Microsoft-powered email accounts. 
     
    We are incredibly sorry for the disruption which this is causing you at present, but we do wish to reiterate that the root cause of these problems resides in Microsoft's own email architecture, not Mailbird's. Countless users of other email applications are reporting the exact same issues online (as can be seen here and here)......"

    Microsoft support is like a rudderless ship with no captain. What is happening here?

    Strange that using OAuth2 on Thunderbird fixed it for you but using OAuth2 on Outlook for Windows did not.

    I already did that. Also deleted the whole Outlook profile and created a new one. Still nothing. I tried both with the main Outlook password and the app password. Nothing works. Or, to put it better, it does work after a number of tries (i.e. the username/pass is correct), and randomly fails afterwards.
