For the past few weeks I have been getting this error, “Microsoft Office Outlook has stopped working.”Then whenever I relaunched Outlook, I got the pop up that said that it was checking the PST file for errors because it was not closed properly. I used the command line option /cleanviews and that still didn’t help.
Check to see if Outlook 2007 is configured to automatically empty the deleted items folder when it exits.  It maybe that Outlook is closing while the deletion process is running.
If you have Outlook configured this way and you would like to try this to
see if this solves this problem, do the following:
To enable/disable this feature, in Outlook, click Tools/Options then click
the Other tab. Remove the check from the box “Empty the Deleted Items Folder
When Exiting.” Now click Apply then OK.
