Using Exchange 2010 SP3 and Outlook 2010 SP1. I just want to remove the option to publish to Office.com. When you right click the Calendar and select Share, one of the options is to publish to Office.com. I want it grayed out or removed completely. How to? GPO? If yes, which setting? been searching for a while now. Can't find it. Seems like it's being depreciated in 2013 anyway.
