Outlook 2019 getting error message

Same issue going on for several hours now using MS Outlook 2021.  I've reached out to support, told them I know the IMAP/SMTP server settings are correct, I even deleted and created a new Secure Mail Key, and still, outlook is asking for a password as if I'm entering the wrong information... there are random times that my email syncs/downloads correctly, then on the next sync, it'll pop up asking for password (secure mail key).... glad to know it's not just me, but AT&T support has been worthless in this regard... even suggested uninstalling/reinstalling MS Office... NOT happening!

Yep thats exactly what I am experiencing, but I am not going to change anything at this point.   Thanks for your response, sorry for a delayed response as I do not get alerts (even though turned on) that some one has posted a comment.  Thanks

Having the same issue for the last day or so.  Fortunately, it syncs on my phone.  Interestingly, I tried several times to create a new secure mail key yesterday  and that failed.  I'm hoping AT&T figures out they have a problem and get it fixed soon.
