Mailboxes are created when you make a new account in Mail.
Changing the name of the mailbox after you have created it, causes problems and there is no longer an account that is matched with the new name.
Rename again and see what happens
Failing that, do you have a backup you can use?

Hi.
My apologies if this problem has already been covered - I haven't seen it.
Yesterday I tried to rename a mailbox (folder) in Mail. As soon as I changed the name, all of its sub-folders (sub-mailboxes?) disappeared except the one I was in. That particular sub-folder still shows its message (email) headers, but each email has lost its contents and is now showing the following error message:
"The message from ... has not been downloaded from the server. You need to take this account online in order to download it."
All the missing sub-folders are sitting in an extra white (greyed-out?) phantom mailbox with the old name, and they are showing no emails at all.
In short, I appear to have lost all the messages (emails) in the renamed mailbox and its sub-folders, and the Undo button in the Edit menu is greyed out.
Can anyone suggest a way to bring them back? Restoring the system to the most recent back-up will mean I will lose a lot of messages.
My version of Mail is 2.1.3 and I am running OS 10.4.11.
Thanks!
