I have an AT&T internet account and Yahoo email both of which are locked. I have tried phone support and in person support at my local AT&T store. Neither can access my account to edit or reset the account. At the moment, my only option is to wait for ATT.Com/myinfo to run a background check to verfy that my email account belongs to me which could take up to 10 work days. So, here is the question...since my AT&T account is locked and I can not access the account to edit or modify information will I be able to install Thunderbird and send and receive email? Or do I have to be able to access my internet account to install Thunderbird? But , if my email is locked and I can not access my email, why am I writing this! Thanks JW
