This is NOT good. Granted I keep tens of thousands of messages in dozens of folders, but they're all important to me in one way or another.
With the Mail conversion that took place as part of my Lion install (conversion by itself took an hour or two), I was left with a message that said my Mail index was screwed, but that it would be recreated after the next restart. Not so! Or at least there's no evidence that anything is happening. When I launch Mail, no windows or messages appear... just the bar at the top. If I right-click the icon in the dock, it says "application not responding".
I know that "application not responding" doesn't always mean that nothing is happening, so I'll probably wait overnight to see if anything has developed by morning.
Anyway, I neeed to prepare for the worst. How do I back out of this new Mail app altogether, so that I can restore my email from Time Machine?
****... I had a nice detailed version of this prepared and it disappeared before I could click the Add Reply button. I don't have the patience to re-enter it all again, so here's the short version.
I started this thread, and I've finally resolved my situation. There are two basic problems it seems.
- The new Mail fails in the middle of the migration. Some have solved that by quitting Mail and simply deleting the files begining with "Envelope" in the Maildata folder inside the Mail folder in your Library. That resets Mail to try the migration again.
- Separately or in combination with #1, when you subsequently launch Mail, only the Mail bar at the top appears.. no mail Window, so you don't know what's going on. This seems to be related to Mail failing to migrate SmartMailBoxes correctly. If you didn't have any before, this probably isn't an issue. Mail goes into an infinite loop trying to do something with SmartMailBoxes, so it has no time to build you a window, and it's even difficult to do a force quit. Force it to quit somehow!
If you've experienced both problems (as I have), make sure Mail has been forced to quit and go into Finder>GoTo>~Library/Mail/MailData and remove anything starting with Envelope and anything with SmartMailBoxes in the file name.
In my case, the migration routine started again and when it was finished, my Mail window opened with the results. Nice! I still had to re-enter all of the account info for my dozen accounts or so, but I think the dust has settled.
As usual, no guarantees! We're all just users helping users here, so I won't accept liability for anything. Where I say "delete", just move the files to your desktop. If the solution doesn't work for you, you can always move them back, and you can't blame me!
It's a pity that the Apple folks don't seem to read what's going on here and update their support files accordingly.
BTW... if this doesn't work for you, there's a long tedious way to do this too... as suggested by others above (in greater detail).
- Quit Mail, and move the Mail folder with everything in it to your desktop.
- Move your email preference file (com.apple.mail.plist) as well to the desktop from Preferences under Library.
- Restart Mail
As I understand it, this should start mail as if you never had email before. You'll need to set up your account(s), then use Import Mailboxes under the file menu to copy in your messages from within the Mailboxes folder in the Mail folder that you moved to the desktop. This should be your last resort, since it'll take you forever to get back to where you were just a few days ago with the previous edition of Mail.
With all this grief I hope the new Mail really does have some good features, because I'm sure not seeing any yet!
