Error?

Same problem here, large hospital/university enterprise. Countless reports of students not being able to book with advisors, and users in general having to play IT with people trying to book calendars. 

This has been going on for a LONG time sporadically MSFT. Your lack of presence in these discussions, and the fact that you point people posting in official MSFT forums to user community boards.. it's pretty sad. Multi-Billion dollar company, and you need you most coveted ambassadors (use admins) to do your legwork. 

Do better.
