Remarks

A handle is a service-side pointer to a session. The handle ID is a GUID identifier of the handle. Callers will usually get the handleId either from another player’s XblMultiplayerActivityDetails via the XblMultiplayerGetActivitiesForUsersAsync() API, or from an invite. Use this method only if your multiplayer session object doesn’t have a valid XblMultiplayerSessionReference, as a handle’s lifetime may be shorter than that of the session it points to.
