Why can I see other BusySync users on my LAN in the BusySync Subscribe tab?
If you do not see calendars being published by other users in the BusySync Subscribe tab, it may be because they have their system firewall turned on and it is blocking incoming BusySync connections. They should either turn off their system firewall, or allow BusySync traffic to pass through the firewall, as described in the Firewall Settings section of the user’s guide.
