I cannot upgrade Exchange due to a the lowest version of Outlook it supports being 2010. I need to use Outlook 2003 for one reason, and one reason only, I can predictably add invitees to calender entries and send invites to them only. I'm hoping this function will be applied to upcoming Outlook versions, but I've seen no mention of it?
or perhaps it's a PEBCAC issue and I'm just not driving Outlook 2010 or 2013 correctly?
