Secure Mail Key stopped working. What's next? Make a new one?
Several weeks ago, we received a notice that we needed to link some accounts within AT&T. Since then, our password for our primary email address (same as the account, we think) stopped working. I created a secure mail key and eventually got our email to start working again with that key. However, a week later to the day, it again stopped. The message was the same as before; "Sending of password for user [our address] did not succeed. Mail server pop.att.yahoo.com responded: Server error - Please try again later."
So what now?.. do I create another secure key? (this would be the third one I've created)... Is there some reason why this one suddenly stopped working again?
I am using Thunderbird and no other settings had/have been changed since this began, and all my other addresses are working just fine.
Called support but they didn't want to help due to us using a third party app. I can pay ConnectTech $15/mo to get their help, but I don't see why I should pay to fix a problem that is clearly originating on AT&T servers.
Webmail for this address works fine, but I do not want to use webmail. None of our other devices can access this address, either.
If anyone has experienced this situation and has suggestions, I'd surely appreciate hearing them. Thanks!
