We migrated our GroupWise WebAccess and owning domain to Linux this
weekend. After doing so, people were unable to open attachments via IE.
I found TID 10086331 and unchecked everything under Disable Caching
via c1 for the GroupWiseWebAccess object under my domain. We restarted
Tomcat and I am still having the same problem.

If I perform the registry hack/fix suggested in the TID everything works
fine, however, I can't control the over 1000 student laptops out there
because we don't own them. I would really like a fix from the admin side.

Anyone have a suggestion as what to look for next?
