How surprised I was to find that Windows 10 is not listed in the approved system requirements for the GroupWise client. Under GroupWise 2014, this is what is listed. Notice, Windows 10 is not listed.

Any of the following desktop operating systems for the GroupWise Windows client:
Windows XP on a 300 MHz or higher workstation with at least 128 MB of RAM
Windows 7 on a 1 GHz or higher workstation with at least 1 GB of RAM
Windows 8 or Windows 8.1 on a 1 GHz or higher workstation with at least 1 GB of RAM
