Cannot add bellsouth.net e-mail account to MS Office 365/Outlook

Did you just create a Secure Mail Key or have you had one previous to this.  I ask because we're seeing more and more SMK's that don't work and need to be deleted and a new one created.

If you still get errors, use these alternate servers instead of the att.com servers.

IMAP

imap.mail.yahoo.com  (use Port 993 and SSL/TLS)

smtp.mail.yahoo.com  (use Port 465 and SSL/TLS)

POP3

pop.mail.yahoo.com  (use Port 995 and SSL/TLS)

smtp.mail.yahoo.com  (use Port 465 and SSL/TLS)

Thank you tonydi.  Creating a new SMK did the trick.

FYI - the old SMK was only 1 month old which supports your observation.

Happy New Year

Glad that did the trick because I was out of ideas!  😁

Just curious, but have you ever gotten a notification about your SMK?

Only notification I got was that I needed one when they first made the change.

Nothing since about renewing or expiring.

Also, nothing came up during set up about needing a "current" SMK ?

No, you shouldn't get those notifications but there's a thread here where people's SMK are getting changed by someone else and they get notified by AT&T each time it happens.  Just wanted to be sure you weren't part of that breach.
