Outlook 2007/3 opening in Safe Mode

Now this may be an old one but there are people out there still using 2007 or 2003
Problem today – Outlook would only open in safe mode and there were no add-ins.

Outlook stores preferences in a number of .dat files which are loaded at startup.

extend.dat – Contains ettings of installed Exchange Client Extensions add-ins and their status.
 Windows XP C:\Documents and Settings\%username%\Local Settings\Application Data\Microsoft\Outlook\
 Windows Vista, Windows 7 and 8 C:\Users\%username%\AppData\Local\Microsoft\Outlook\

outcmd.dat – Contains toolbar customizations
 Windows XP C:\Documents and Settings\%username%\Application Data\Microsoft\Outlook\
 Windows Vista, Windows 7 and 8 C:\Users\%username%\AppData\Roaming\Microsoft\Outlook\

Rename both files and restart outlook.
