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

    thank you! I didn't know that OAuth2 could be used. Now you don't have to rely on app passwords.

    Also, the problem of being asked for authentication information multiple times seems to have been resolved in my environment.

    No problem.

    Even though app passwords are now functioning, it's worth switching Outlook 2013 to OAuth2 in case this happens again.

    It seems that the problem of being asked for authentication information many times has finally been resolved in my environment.

    Yes, I'm seeing this too.

    Hotmail account on Outlook 2013.

    Modify the registry and you won't need any app passwords:

    So, is Fetchmail working this entire time? Do you have specific clients that use OAuth on the personal side? I use 9Folders, that only allows OAuth on business accounts.

    50% to 80% of my connection attempts with Fetchmail failed, until about 3 hours ago. Now 100% succeed.

    I have no idea why 9Folders would only allow OAuth2 on business accounts.
