Use IM
If it has been enabled in the server settings, MultiPoint Dashboard users and station users can exchange private messages over IM.
To send a chat message from the MultiPoint Dashboard to a user
In MultiPoint Dashboard, click the thumbnail image or images of the user you want to send a message.
Click Send in the ribbon - an IM chat window opens.
Note
Users can IM the dashboard user by using the IM icon in the Windows taskbar. It is automatically pinned when IM is enabled in the server settings.
