Here is a bit more info.
It is Exchange server 2003 Standard SP2. The calendar is a shared
private calendar. The user can view the calender in Outlook 2007 but
not create any appointments. She just gets the error "The object can
not be found". In Outlook 2003, everything works fine so I don't
think it's a permission problem on Exchange (at least not something
obvious). We're also able to view and edit several other users
calendars in 2007 fine, it's just this one user's calendar that can't
be edited. We tried to set up a new computer with a fresh install of
Windows XP SP2 and Outlook 2007 and get the same error.
<UPDATE> Ok.. I just solved this so I'll post the solution for
reference.
1. Open Outlook 2007 under the account of the calendar owner.
2. View the calendar. Right click on "Calendar" under My Calendars on
the left pane and select properties. Open the General tab.
3. Find the area that says "When posting to this folder use:" with a
list box beside it.
4. Make sure it's set to IPM.Appointment.
In this case, the original user had WebEx Office installed at one
point and it was still trying to use some WebEx specific plugin to
post appointments. I still have no idea why this does not
detrimentally affect Office 2003.
