If I open tab "Send Options" I could see and define sned options - ich I change back to Mail-tab it is leaving empty.

I tried a clean reinstall of GroupWise client - tried to open a view directly from the ofviews/win directory.
It depends not on a single user - because it happens on different users. It depends on this pc because opening mails on other client pc works fine.

Does anybody have an idea what this problem could cause and how to resolve it?

Thank You,
