I have exhausted all other resources for trying to get the spell check function to work within Groupwise 6.5.6 when installed on Citrix Presentation Server 4.5.
Everything works fine with the exception of the spell checker, and some users are not happy without their spell checker.
1. Re-install the Citrix server.
2. During the Terminal Services portion of the setup, choose “Relaxed security”.
The GroupWise spell checker should now work fine.
