Running Exchange 2010 SP1. Using Outlook 2007.
I have a mail-enabled public calendar.
If I create and appointment from my Outlook calendar and invite this public calendar as a resource, it shows up in the public calendar so all is good.
If I edit the appointment from my Outlook calendar it sends a second appointment to the public calendar. So the public calendar now has the original appointment and the modified appointment.
Is there a way to have the original appointment on the public calendar updated without creating a second copy?
