Tbird 60.7.0 has been accessing free AOL email for several years as set up for Verizon.net email users. As of 5/22 cannot send emails. Error message is "An error occurred while sending mail. The mail server responded: Request failed; Mailbox unavailable. Please check the message and try again." My ISP is Frontier FIOS who do not provide tech support for AOL email. Called AOL. They do not provide tech support for free email accounts. I can receive emails via POP, but cannot send via SMTP. Setting is smtp.verizon.net; Port 465; SSL/TLS. I have not changed anything in my account settings. I believe it is problem with AOL server, but don't know how to find out. (Phone rep suggested I open AOL account, get tech support, then close account before 30 day trial ends. Wanted credit card. I said NO.) Any help would be appreciated.

Thanks for the reply. I didn't try that, but I do have a "reply to" address." I gave up on AOL and moved my main email address to my ISP, Frontier. (Everything is forwarded.) It took a while to set up Thunderbird, a combination of needing "full" user-id (ie: @xxxxx) and possibly conflict in the Tbird Password Manager. I deleted all old PW's and forced it to ask for new ones and finally everything worked. The failures in both AOL and Frontier were in accessing the SMTP server, but Frontier's worked. I tried the same fixes with the AOL server, but nada. Still a mystery, but no longer my problem. Thanks again for the help.

Do you have a reply-to address setting? Removing this fixed the problem in my case. Don't know why this should be a problem.
