If you have deleted one or more users with the Calendar Server Utility command csuser delete, or with Delegated Administrator Console or Utility, calendars owned by that user might still be present in the database.
There are two ways to remove users’ calendars. The method to use depends on the tool you used to delete the user:
The csuser utility removes the user from the LDAP directory and removes the user’s default calendar, but not any other calendars the user might own. For instructions on how to use cscal to remove these calendars, see To Remove All Calendars of a User Deleted with csuser.
Delegated Administrator does not remove any calendars. Use Delegated Administrator to mark users for deletion and then use Calendar Server Utility csclean to remove calendars for user's marked for deletion.
For instructions on how to remove deleted users’ calendars using csclean, see To Remove All Calendars for Users Deleted by Delegated Administrator.
For instructions on using Delegated Administrator Utility, see the Sun Java System Communications Services 6 2005Q4 Delegated Administrator Guide.
For instructions on using Delegated Administrator Console, see the online help.
