Start a Microsoft Office 2007 program in Safe Mode

This is really simple, and can help diagnose issues and problems you may be having with Microsoft Office products, such as Word, Excel, Powerpoint, and Outlook. In order to start the application in safe mode, simply hold down the Ctrl key when selecting it from the Start menu (Start->All Programs->Microsoft Office, then pick the icon of the program you want to open). You will be prompted asking if you want to start the application in safe mode, so assuming you do, select yes to continue.
