Outlook 2010 security settings are greyed out
A fix suggested by an IT consultant for one of our customers:
"I created a new group policy object using the Outlook 2010 Administrative Template files (must be download here http://www.microsoft.com/downloads/details.aspx?familyid=64B837B6-0AA0-4C07-BC34-BEC3990A7956&displaylang=en). I never found a pre-existing policy that set the macro settings, and everything I read said there is not supposed to be any such policy applied by default by Exchange or SBS 08. The policy that I created changed the settings, however they are still grayed out in Outlook."
