Error: The item attributes cannot be changed...(due to overlapping appointments)
Error:
The item attributes cannot be changed. Only one appointment can be scheduled for a single time period on this schedule when the Disallow Overlapping Appointments option is in effect.
Cause:
This error occurs when attempting to edit overlapping appointments after the Disallow Overlapping Appointments restriction has been enabled. This is by design.
Solution:
To edit overlapping appointments, disable Disallow Overlapping Appointments.
1) Select the 'Tools' menu and select 'Set Access Permissions...'.
2) Clear the 'Disallow Overlapping Appointments' check box.
