Outlook 2007 Error – The requested operation failed

I came across an issue I’ve not seen for some time at a Client’s this evening. When you open Outlook and try and click on your archive folders or mail box folders you receive an error stating:

“The requested operation failed”

To resolve this issue, follow these steps:

Locate Outlook.exe.
Outlook.exe is typically located in one of the following folders, depending on the version of Outlook that you are running:

Outlook 2010 – C:\Program Files\Microsoft Office\Office14
Outlook 2007 – C:\Program Files\Microsoft Office\Office12
Outlook 2003 – C:\Program Files\Microsoft Office\Office 11
Outlook 2002 – C:\Program Files\Microsoft Office\Office 10
Outlook 2000 – C:\Program Files\Microsoft Office\Office 9

Right-click Outlook.exe, and then click Properties.

On the Compatibility tab, untick the “Run this program in compatibility mode” checkbox.

Outlook 2007 compatibility mode

Click OK.
Now start Outlook.
