Outlook Permissions for ICS files

A user recently got the error: "Can't create file: calendarevent.ics. Right-click the folder you want to create the file in, and then click Properties on the shortcut menu to check your permissions for the folder."

After some serching, it is not really a permission problem but rather when you install certain Microsoft Small Business products, the OutlookSecureTempFolder key in the registry is changed from "..\Temp\..." to "...\Temporary Internet Files\...".

To fix this, have your system administrator, go into the registry and change the HKEY_CURRENT_USER\Software\Microsoft\Office\11.0\Outlook\Security registry key OutlookSecureTempFolder value from "...\Temporary Internet Files\..." to "...\Temp\..." and you should be able to open ICS events from QuickPlace or any other service again.
