On this end, Exchange 2010 SP2 UR6, Outlook 2010 client. When external user sends a meeting request, user's Outlook hangs and grays out. This does not happen with internal meeting requests. Googling around I find where this can be because Outlook goes and tries to gather all the Free/Busy info first. So, I can understand that, but while I can find an explanation, I am unable to find a solution.
Has anyone out there ran into this? -Paul
