One of our internal support guys (HarryP) came to me earlier with an error which we rarely see regarding using CRM 2011 through the outlook plugin and being faced with “CRM failed to load” error, as we generally use CRM through IE.
The solution is simple:
Close down Outlook.
Search for “Diagnostics”
Diag
 
Click on the ‘Advanced Troubleshooting’ page and press ‘Enable‘ under the ‘Microsoft Dynamics CRM for Outlook Add-In’ section:
Diag2
Save the setting and restart outlook.
Cheers,
Jason.
