Best practice is to delete appointments from the Suite application to remove the appointment from Microsoft Outlook. When an appointment is deleted in Suite, it is removed from the Outlook calendar during the next synchronization. For information on deleting appointments in Suite, refer to the Calendar section in the Secretariat User’s Guide or the eCounsel User’s Guide.
Deleting appointments from Microsoft Outlook will remove the invitee in eCounsel or Secretariat. However, if the invitee is re-invited to the appointment in eCounsel or Secretariat, the appointment will reappear on the person's Microsoft Outlook calendar.
