Messages sent to the participant's sever will always be addressed to the user's bare JID. The participant’s server will modify the recipient to the full JID of each client to which the message is forwarded. The following example, repeated from &xep0369;, shows a message distributed by a MIX channel and directed to the participant’s server with the participant's bare JID.

A user setting status is now used as an example. Unlike in &xep0045; where coming online is a special action, coming online in MIX is implicit when presence status is set. Going offline is a achieved by setting presence status to unavailable, which removes the client full JID entry from the presence node. When a user sets a presence status, the user's server sends updated presence to the MIX channel, and the MIX service then publishes the user's availability to the presence node. If there is not an item named by the full JID of the client with updated presence status, this item is created. The sequence is shown in the following examples, starting with a client setting presences status on the connected server.</p>

The server then sends the presence information to roster entries. The following example then shows the presence message from the client's server to the MIX channel. The presence is then handled as specified in &xep0369;.

When a client goes offline, it will cease getting presence updates. Presence updates will continue to flow to the user's local server, and so the local server is able maintain up to date presence state for the channel, even when there are no online clients. When a user had no online clients the user's server MAY continue to maintain MIX presence status for the user or MAY discard inbound MIX presence information.

The client receiving the presence can parse the proxy JID, specified in &xep0369; to identify the channel to which the message relates. The proxy JID can be looked up in the Participant's node to determine Nick and real bare JID. The real bare JID can be combined with the resource form the presence stanza to determine the full real JID of the sender. This is described in &xep0369;.

The second scenario is when the MIX participant's server needs to load or refresh presence status for a channel. This will be needed when the participant's server is started or when the server chooses to not maintain presence for a user when all clients go offline. This MIX participant's server requests presence update by sending a directed presence stanza to the MIX channel from the user's bare JID. The MIX channel can distinguish this from a presence update, which will always be sent from the clients full JID. This will cause the MIX channel to send a full presence update for the channel.

Presence information is provided with a proxy JID. A MIX client will usually wish to map this to the real JID. This will be done using the participants node, which has a list of all participants identified by proxy JID with real JIDs where this can be shared. Where real JIDs are not available, the Nick will be available. Clients will typically load the participants node on start-up and use a subscription to the participants node to keep this up to date.
