Thanks to Dan for posting a fix to the Outlook crashes that many people have been experiencing. It all turned out to be Cloudmark ..here’s the fix.

In Vista, go to C:\Users\[Profile Name]\AppData\Local\ and rename the Cloudmark folder to Cloudmark.bad.

In XP, go to C:\Documents and Settings\[Profile Name]\Local Settings\Application Data\Cloudmark and rename the Cloudmark folder to Cloudmark.bad.

Then start up Outlook and you’re good to go. You do not need to uninstall or reinstall Cloudmark.

UPDATE:

In order to preserve your whitelist settings, you’ll want to copy 2 files over from the old directory to the new directory.

1. Close Outlook.
2. Copy the files cdol_firstunblock.dat and cdol_whitelist.dat from your old \Cloudmark.bad\SpamNet directory to your new \Cloudmark\SpamNet directory.
3. Restart Outlook.
