Resolved Mail Wont Launch

[RJ17]

I am having an issue with mail.app on ML. The first launch worked fine but the app hung on finding conversations. Now when I launch the app it will just hang until I force quit. Any ideas?

When I launch mail it immediately uses 100% of the CPU and will stop responding in less than 5 seconds.

You might try just letting it work for a little while, even if it's unresponsive.

I tried letting it run all night but it was still hung when I woke up.

Tried Disk Utility but still not launching.

Is there a cache to clear or some other action to take. I would rather not reinstall ML. Is there a way to may mail think it is the first launch again?

This is the error in the all logs.

I had these "deny file-read-data /Library/Preferences/com.apple.mail.plist" sandbox errors before. They were not causing any freezing problem, but they were flooding my console log. So I searched around and found that deleting the mentioned file might fix the problem. So I did, and the message did go away.

I tried deleting the file and that did stop the errors but didn't change anything with the app.

Give this a shot, first quit Mail then click on your desktop to bring focus to the Finder. Press shift-command-g and you will get a popup. Enter ~/Library/Mail/V2/MailData in that popup and hit enter. Look in that folder for a file called Envelope Index and delete that file. Now restart Mail. It should begin a fresh indexing of your mail folders/messages.
