I have a ignorant friend that just upgraded from Panther (10.3) to Leopard (10.5) via the upgrade method and did not backup before hand. His issue is that the Mail conversion didn't complain, but all mailboxes contents were missing. The Inbox folder in Mail was empty and Drafts was completely missing, as well as some other system generated folders (AFAIK). Other user created folders were in Mail on the left, but were empty. We were able to import the Foo.mbox folders into Mail, so we got the user created folders contents back, but that doesn't help for drafts or few hundred emails in the inbox. Apparently in Panther, the mailbox was in a directory with a name something like ~/Library/Mail/POPemail@example.com, and now in Leopard, it is somewhere else. Anyone have thoughts on this one. I looked for the old directory, but could not find it. What happens with the directories when the Leopard upgrade works on it? Is it left around but in /tmp or something? Any help would be highly appreciated and successful recovery might result in a reward of the kindest of words!
