+The ResetDelegateUserCollection switch can only be used together with -Identity parameter, and the value of Identity should be the user's primary calendar folder, for example, [email protected]:\Calendar. If you run into a problem when trying to add, change, or remove delegate permissions, it is possible that the delegate information stored in the LocalFreeBusy item or the PR_FREEBUSY_ENTRYIDS has become corrupted. Including this switch will delete those files and will downgrade any existing Delegates to Editor status. You will need to grant Delegate permissions again using -SharingPermissionFlag Delegate.
