Remove a Contact Group

A contact group is an instance of the groups category. To remove a contact group on Office Communications Server, the removed contact category instance must be published to the server with the operation type UCCPOT_REMOVE.

Removing a contact group involves the following steps:

  • Create a publication manager object by casting an IUccEndpoint object into an IUccPublicationManager object. The publication manager is responsible for creating a publishable category instance object and publication object.
  • Get a publishable category instance representing the group to be added by casting the IUccGroup interface into an IUccCategoryInstance.
  • Set the publication operation on the publishable category to be removed by filling the PublicationOperation property using a Unified Communications Client API enumeration value UCC_PUBLICATION_OPERATION_TYPE.UCCPOT_REMOVE.
  • Create a publication object by calling CreatePublication and casting the returned value to the IUccPublication interface.
  • Register for publication events to catch the asynchronous response to this publication request.
  • Add the IUccCategoryInstance created earlier to the publication with a call into AddPublishableCategoryInstance.
  • Publish the group by calling the Publish method on the publication object. In this example, the optional operation context is not supplied with the request.
public void RemoveGroup(IUccGroup group)
{
   try
   {
     IUccPublicationManager pubMgr = endpoint as IUccPublicationManager;
     // Get the publishable category instance for the contact to be removed
     IUccCategoryInstance cat = group as IUccCategoryInstance;

     // Set publication operation on the category to Remove
     categoryInstance.PublicationOperation = UCC_PUBLICATION_OPERATION_TYPE.UCCPOT_REMOVE;
     IUccPublication pub = pubMgr.CreatePublication() as IUccPublication;
     UCC_Advise<_IUccPublicationEvent>(pub, this);
     pub.AddPublishableCategoryInstance(cat);
     pub.Publish(null);
   }
   catch (COMException ex)
   {
      Console.WriteLine(ex.ToString());
   }
}
