After uninstalling Office 2010 Pro. and installing Office 2013 Pro. Outlook will not launch. The error message is an insightful and thought provoking "Cannot start Microsoft Outlook" which immediately provide a solution!

I have fully patched this version of Outlook, tried disabling all my add-ins, and tried disabling "hardware acceleration mode" to no avail. Our UAC settings are the MS recommend settings for enterprises pushed out via a GPO policy.

I can only start Outlook in "Run as administrator" mode or in safe mode (outlook.exe /safe).

Any suggestions would be appreciated...

Please browse the Outlook.exe application from the path:

C:\Program Files\Microsoft Office\Office 15\Outlook.exe

Or

C:\Program Files (x86)\Microsoft Office\Office 15\Outlook.exe

Right click on Outlook.exe (application) -> Go to Properties, under Compatibility tab -> uncheck the compatibility mode -> OK

Launch Outlook again to check if everything is fine. Good Luck.
