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

    What version is your Office 2016? If it's not close to mine go to Windows Update > Advanced Options, and enable "Microsoft Update", Win11 setting below. This will ensure you have the latest Office updates.

    Check if you have this registry key set that tells Outlook to connect with Modern Auth. Its not normally needed but worth trying, How modern authentication works for Office 2013 and Office 2016 client apps - Microsoft 365 Enterprise | Microsoft Learn.

    HKEY_CURRENT_USER\SOFTWARE\Microsoft\Office\16.0\Common\Identity\

    Dword:EnableADAL

    Value:1

    Thanks for your help .... but why (within the last 2 days) is this suddenly not working?

    I have had Office 2016 for the last 4-5 years hooked up to my ******@HOTMAIL.COM !??!?

    Does not make sense ....

    And I'm not alone with the problem.

    Regards

    Hi Gabe

    Thanks for the try ...

    ... Same Office 2016 version as you

    ... Did the Regedit fix .... same problem! Asking for password :-( ... and now I don´t get any mails. I did yesterday - but could not send mails.

    Now its "all dead". The Windows 11 mail APP is working .... so it is NOT a password thing.

    I still think this is a World Wide Microsoft problem that started 2 days ago ... :-/

    Regards
