Mail upgrade in Lion crashes

Question

After downloading Lion and launching Mail for the first time, Mail crashes in the middle of the Upgrade during the Optimizing part. Anybody else having this problem?

Answer 1

One method that was posted overnight by traversario in another thread (p. 2) is called the "brute force" method: just keep opening Mail up every time it quits during optimization and eventually it will stop quitting and go on to the next step. I tried this, and mail eventually did open, but it currently doesn't show any of my locally stored mailboxes.
It's still processing (10 different processes in the Activity window: updating caches, etc.) so I'm hoping they will show up eventually. Once you do get to Mail after optimizing/etc., there is an option to import mailboxes under the File menu, so I may try to import mailboxes through this means if they don't show up, but others reported that the brute force method worked for them.
There is a different solution by FishNYC22 in the same thread (p. 2) which involves using a Time Machine backup and moving/ replacing files in the now-hidden Library for your user. I didn't try this one out the other method seemed to work at first for me (but didn't completely), so this is another option.
