Mail Won't Launch

    When I open Mail for the 1irst time after installing Lion, I get the dialog box popup that says that my messages need to be upgraded the first time I use mail.

    "Click Continue to upgrade your messages now, or click Quit to upgrade later."

    I click continue, and the box changes, indicating the messages are being upgraded, but it immediately quits. The upgrade boz is not even up for a half second. Trying to launch mail again brings me back to square one, and the same thing happens again.

    I practice inbox zero and all of my accounts are IMAP, so I can't imagine it's choking on my inbox load.

    Has anyone experienced the same problem? Any ideas for solutions? I tried searching to no avail. Thank you.

    I had this same problem with Mail when it tried to upgrade my database. I ran SpeedMail ( and that fixed it. I'm not sure exactly what it does, but I'm guessing it cleans up Mail's cache and/or index. Give it a shot and let me know if it works.

    I had a similar issue with Mail (it kept freezing) until I restarted my MBP..then, no problems since...

    Speedmail worked - thanks!

    I found this thread after googling my Lion Mail upgrade problem (same as OP). Thanks GadgetComa for the suggestion to use Speedmail - it fixed it.
