In order to view the schedule of meetings held in a remote workgroup, go to the Meeting List view in Meeting mode and select the meeting list drop down. Select the remote workgroup which will be shown towards the bottom of the list. This will open the remote workgroup and will display the structured list of meetings. Clicking on a meeting using the left mouse button will display the list of people invited to that meeting in the Members window at the bottom of the Meeting view.
You cannot book a meeting directly into a remote workgroup, however you may book a meeting from the local workgroup consisting of members from a remote workgroup.
