   [in] IDispatch* pContact,

Return Value

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


This event is returned when the Office Communicator server has successfully removed a user from an ongoing conversation. The Office Communicator UI places the removed user in the Recent Contacts group within the UI because of that user's prior interaction with the local client user. The Recent Contacts group contains the last 10 users that have interacted with the local client user. To make the removed user a permanent contact, this event handler should generate a request to the Office Communicator server to add this user as a permanent contact to the local client contact list. See IMessenger::AddContact for more information.

Note: The pContact parameter is cast to the IMessengerContact interface to gain access to the properties necessary to do work. This contact represents a temporary interaction with another user within an IM conversation. This IMessengerContact user object might not be a member of the local client user's contact list. Using the IMessengerContacts collection, an application can determine that the user is not a member of the local client user's contact list.


The event handler displays the HWND of the IM window opened for a conversation and the friendly name of the contact removed from the conversation. The two parameters of this event handler must be cast to appropriate interfaces to access the properties needed to display the values in the application console window.
