Hi! After I upgraded my Macbook Pro into Mountain Lion, I noticed that Mail is now much slower. Aside from that, it keeps on quitting unexpectedly. How can I resolve this? Thanks

MacBook Pro, OS X Mountain Lion (10.8.2)

    Please follow these directions to delete the Mail "sandbox" folder.

    Back up all data.

    Quit Mail.

    Triple-click the line below to select it:

    ~/Library/Containers/com.apple.mail

    Right-click or control-click the highlighted line and select

    Services Reveal

    from the contextual menu. A Finder window should open with a folder named "com.apple.mail" selected. If it does, move the selected foldernot just its contents — to the Desktop. Leave the Finder window open for now.

    Relaunch Mail and test. If the problem is resolved, you'll have to recreate some of your Mail settings. You can then delete the folder you moved and close the Finder window. If you still have the problem, quit Mail again and put the folder back where it was, overwriting the one that may have been created in its place. Post your results.

    Caution: If you change any of the contents of the sandbox, but leave the folder itself in place, Mail may crash or not launch at all. Deleting the whole sandbox will cause it to be rebuilt automatically.
