I mapped in my zimbra calendar into ICAl on snow leporard upgraded from Tiger.
The calendar mapped in fine but I cannot edit the appointments or create a appointment. I did not use the Aplle ISYNC. I mapped the calendar in manually.
I setup the calendar in ICAL by ICAL - Preference - Accounts - Account type ( Automatic ) . Then Account type ( CalDav ) then my Zimbra server details.
This gets my calendar mapped in, but as I said I am unable to edit the appointments or create appointments.
The error message I get is :
Only the calendar administrator and any delegates with permissions can make changes to read only calendars. To make changes to the calendar , contact the calendar administrator.
Has anyone else come across this error message ? If so how did you resolve this ? Any help would be much appreciated.
