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 have not received any emails or any other updates on Nine Folders since Jan 26th. Nine is an Outlook for Android. I tried to wade through the 37 pages of responses but couldn't find the answer. Is there a fix?

    I do not know if it is fully fixed since there are sometimes hours without problems and sometimes only new password prompts and no authentification possible.

    But you can try this:

    Make sure that you have switched on two-factor authentication in the relevant account. If you already have, please also set up a new app password (if Nine does not support 2FA for microsoft accounts). Then try to newly set up your account (delete it first and then try a fresh set up).

    Try to set it up as:

    1. EAS with server outlook.office365.com
    2. EWS with servers m.outlook.com and/or s.outlook.com

    Try all this with both, WLAN enabled and disabled (so only mobile network)

    It could be that this will fix your account since I guess that its not only a problem with their servers but also with some accounts or some account status on their servers.

    BTW: For me since today morning all works fine with my account set up as EWS with 2FA on and App password. But I did not leave my WLAN for today, so it could be that I will still get errors later on. :-)

    Edit: As I do not know Nine at all I do not know what this app/programm supports but after skimming the website, I think that at least one of the protocols mentioned above should be supported.

    Early in this post (sorry, don't remember which page), there is a post about a new release from 9Folders that supposedly works around the problem. It's a new update to the app. I use 9Folders also, but haven't had a problem in days, and when I did, it was hit or miss, so I lived with it, waiting for a fix from MS. Still don't know if it is fixed, but no issues on my end for a while.

    A little add from my side: Directly after leaving my WLAN Network I got a password prompt. After I got back to exact this WLAN network again (about 15 mins later, so same public IP address) I got my mails pushed again without touching the new password prompt, so it was working again.

    Perhaps this helps identifying the problem.
