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