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
