We are using Outlook 2007 with Exchange 2003. I have a recurring appointment set up on a shared calendar. Permission is granted to everyone to edit, delete, create new, etc. When that appointment is edited by someone else, it turns into what looks like an email. In other words, when I open the edited appointment the send button appears along with all the other standard email buttons. The standard calendaring buttons are no longer there. At the top it says "Message" instead of "Appointment". I also can no longer edit this appointment or delete it from the calendar unless I go to the workstation that the calendar belongs to. I can delete and edit other appointments on that same calendar and they still appear as appointments when I open them up, unlike the recurring one I just described. Any ideas?
Software/Hardware used: Outlook 2007, Exchange 2003
