Using Thunderbird to access Verizon account on AOL server. Suddenly 2 of my sub accounts will not send outgoing emails on one computer. Tried deleting one account and reinstalling. Did not make any difference Here is error message that pops up immediately after hitting "send": "Sent error message Sending of message failed. An error occurred sending mail. The mail server responded: Request failed. Mailbox unavailable. Verify that your email address is correct in your account settings and try again." I can send when on AOL server direct, but not with TB. Have not changed anything. It was a real bear to reinstall the account with their app password requirement for third party apps. It is set up ass IMAP. How do I get this fixed?

Figured it out. You need to have an Outgoing server tab for each email address. You do that in the Outgoing server list where you can add/delete profile links. If you change them by going to each email address account and bring up the tab on the right for outgoing server, that change will affect all your addresses not just the one you want and the problem will still exist.
