Original Title: "I am unable to open Outlook."

I receive the following error:

Microsoft Outlook cannot be opened because of a problem.

Check with the developer to make sure Microsoft Outlook works with this version of Mac OS X. You may need to reinstall the application. Be sure to install any available updates for the application and Mac OS X.

Word, Excel, & PowerPoint are working fine.

I have looked for updates to Lion as well as updates for Office and am told that there are none available.

I am running OS X 10.7.5 and the latest edition of Microsoft Office 11.
