said by CharlesH1:What about sub-accounts? My DSL account is a pacbell.net e-mail address, with several sub-account pacbell.net addresses. While from the discussions here, I am confident that the main address would be converted to a "free" yahoo account, I haven't heard what happens to sub-accounts if you terminate your DSL service.
I terminated my two AT&T DSL accounts in March 2011, and all of the att.net and bellsouth.net email accounts were/are still accessible through the ATT/Yahoo! email servers. I am also still able to access them through »
www.att.com/olam/dashboa ··· mexecute to make changes and even create new sub accounts. Also, none of them have yet been converted into "free" Yahoo! accounts; I still have full POP and SMTP access to them.
I can't however, guarantee anything for your situation because my impression is that it is somewhat just the luck of the draw as to what will happen to any individual account when it is terminated. Some have reported that they still have full access just as I do, and some have reported that the accounts were closed (or made inaccessible due to authentication problems which neither AT&T nor Yahoo! seem interested in resolving once you are no longer an AT&T customer).
You may want to do what I did prior to terminating my two DSL accounts. I setup all of the AT&T email accounts to forward to another (non-AT&T) email address, and later, after I verified that the AT&T accounts were still accessible, I removed the forwarding.
