We have an employee that wants to sync her iphone with the outlook calendar in the office. When she did this it ended up creating 2 "modcal" Calendars. The problem is now her main calendar is the sub calendar. Meeting invitations are going from some people to one calendar and others to the other calendar. Moral of the story...this is a mess. Is it possible to combine the 2 calendars? Is it possible to delete both calendars and reload the information from a backup? Does anyone know of anyone that would perform support on this strange issue if we don't do it ourselves?
