Restarting after each update refreshes the file that tells updaters what version is installed. This is supposed to happen automatically but often fails. Restarting forces this file to update.
In your case you'll probably need to re-install. If you have one of the original install CDs, you can download the trial so you start at 14.2.0 (it's possible they have refreshed it to 14.3.0). You can use your CD Key to activate. Whatever you do, update past 14.2.0. It was full of problems.

**This Identity Cannot Be Opened With This Version of Outlook"
This message usually means any Identity saved with a newer version will not open in an earlier version. We see this a lot when users do a re-install of Office then fail to upgrade.
There was a database upgrade in 14.1.0, 14.1.3 and again in 14.2.0. Until you update the Identity will not open.
Disable Apps:
Log out under Apple in the Menu bar. When you log in, hold down the Shift key. This disables all login items including the hidden ones like the Microsoft Database daemon and SyncServicesAgent. All browsers must be quit to update.
