I am trying to change the username on an existing Thunderbird email account to another user name. I have the name changed and can send email out from it. However, you cannot treply back to the email, you get an error message saying that the address does not exist. Nor can you receive an email sent directly to the account with the changed name.

Thank you,

Judy Pfeffer

Is the new username an established email account with an email provider? If not, that is your problem. You cannot just make up a username and expect to receive email with it.

I would not suggest changing usernames due to a new email account. I would set up a new account in Thunderbird for the new email account.
