We have an issue where the extensions for file names are being converted from lower case to upper case - EG thisfile.html become thisfile.HTML as an attachment. The issue began when we applied service pack 2 for GroupWise 8. It also appears that it only occurs when sending files between post offices - a file sent to someone in my own PO is not changed, but one sent to another PO is. We've tested between several post offices, and see the same results.

Any ideas?
