I have multiple verizon.net email accounts on t-bird. All receive mail. I can only send from one of the verizon.net accounts. Error message says "Request Failed; Mailbox unavailable"

Thank you for your response

The account is labeled "Default" is the account that does send. Each of the other verizon.net accounts shows their own named server as outgoing. I have tried moving the default label to other accounts, but to no avail.

Thank you for your response.

I tried most of what you suggested but to no avail. I think it is a verizon quirk. TBird allows me to send from as many GMail accounts as I need, so I will shift my (mostly) receive only accts from verizon to gmail.
