HRESULT OnContactRemovedFromGroup(
   [in] LONG hr,
   [in] IDispatch* pMGroup,
   [in] IDispatch* pMContact
);

Parameters

The implementer of this event handler will determine what value should be returned.

This event is used to notify the client application that the Office Communicator server has attempted to remove a contact from a user contact group. If the hr parameter indicates success, the contact has been removed from the specified contact group.

The request to remove a contact from a group is made by the local user but the action is performed by the Office Communicator server. If the client application is keeping a current list of contacts, you should use this event handler to cause the update of the client list.

The following example code displays the name of the contact and group in the application console window. To do this, the code casts the generic object method parameters into the correct IMessengerGroup and IMessengerContact interfaces. Using these interfaces, the code has access to all the methods and properties required. The myContactList object represents a local application custom contact list.
