I installed CalDAV on the GroupWise server and now the Webaccess redirects to a CalDAV welcome page. If I disable the CalDAV service. Web access still doesn't work. I believe this to be a port 443 conflict.

Is is advisable to for instance change the CalDAV or WebAccess to use a different port? Is so how do I go about doing this. Can it be done the the GroupWise Admin Console?

Otherwise is there another solution to get GroupWise Webaccess working? (The WebAccess is a priority)
