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

    Life's just too short to waste ANY of it troubleshooting this Microsoft-caused mess they clearly have no intention of fixing. Nearly six weeks of this and there's no end in sight. They can have it. Switching to another provider and I'm done.

    Is there any Solution for GMAIL on Android? It´s possible to use "modern authentication" but then it can´t connect and gives me an error message...

    I can’t say anything about EAS because I did not test it.

    EAS is a protocol designed for mobile, while most desktop clients use the EWS (Exchange Web Service) protocol.

    I tested this a lot and tried to reverse engineering the communication of several desktop app to understand what’s going on.

    The conclusion: EWS does not work with OAuth for personal Outlook accounts with one exception: Apple Calendar. For some reason they can use it.

    Never got an official reply from MS on this matter. My understanding is that EWS is being deprecated and therefore they don’t want vendors to keep using it. Apple probably got a special del to be able to keep using it.
