The WorkgroupShare client must be installed on each computer that will share and use data, such as contacts and calendars, with Microsoft Outlook.
This Setup Type screen gives the option to share the WorkgroupShare ClientSetup folder located at:
"C:\Program Files\Ipswitch\IMail\WorkgroupShare\ClientSetup", if default path was selected.
Ipswitch recommends sharing this folder across your network for client efficiency.
