This module is on a DX58SO2 running Win 7 Pro x64 SP1 & MS Office 2007.
From what I've researched, the issue is also valid for Office 2010.

PS
A tech rep from the Microsoft Support Community indicated that the issue isn't resolvable if the manufacturer implemented their add-in in the wrong way. It is not a native Outlook or Windows feature. Also, to contact the manufacturer to determine if updated drivers are available.
