In accounts in hotmail except inbox all others have disappeared?

Question

In hotmail account except inbox all have disappeared.

Answer 1

For now, we are not going to quit mail until we hear something back.
This is pure paranoia and has no basis in fact. Things don't spontaneously disappear when you quit an application, and since you later state that you've backed up the Mail directory, that's another reason why your reasoning makes no sense. Why don't you try a simple solution:
1. Quit Mail if it's running.
2. Go to ~/Library/Mail and delete the Envelope Index file.
3. Restart Mail and wait for it to import your existing messages. When it's done, check to see whether your mail is showing correctly in your Inbox for your accounts.
