Returns an IMsgServiceAdmin pointer for making changes to message services.
[in] Reserved; must be zero.
[out] A pointer to a pointer to a message service administration object.
The IMAPISession::AdminServices method creates a message service administration object, an object that supports the IMsgServiceAdmin interface and returns a pointer. By using this pointer, you can call IMsgServiceAdmin methods to change any of the message services in the session profile. Be aware that these changes do not take effect until the next session; the current session is unaffected.
