May be not relate directly to your issue, I have noticed deleting Field Definition was difficult process in earlier version of GroupWise 6.5. The program I used, delete the Field Definition in current GroupWise session but the Field Definition reappear on restarting GroupWise. The Field Definition eventually deleted if I run the program few times. I don’t know whether this behaviour changed in GroupWise 6.5 or GroupWise 7. I will test the program in GroupWise 6.5.4 and let you know the results.
