Apple Event: May 7th at 7 am PT
Using OSX Mountain Lion. On start-up all accounts in Apple mail disappeared. (I have several accounts, all types, all gone.) Also, I tried to find the MAIL folder in the Library on my Time Machine back-up, but it's missing, too.
Open Mail, enter Time Machine (from the menu bar) and scroll back in time until the accounts reappear.
Unfortunately it's much more complicated than that. In order to retrieve all accounts, permissions, etc., I need to find the info in the system Library, which also seems to be missing from Time Machine.
OK, do it your way.
