Is there a specific procedure for renaming users in GW8? I am having problems renaming some users in that when they get renamed the client says " A problem with your mailbox has been encountered", similar to document 7007057 except I am not getting any errors when I run gwcheck. If I put them back to the original name they work fine. I have checked to make sure the file is not locked by a backup or something else. Display object shows a "Move error 0xd109 - Bad parameter" Renaming worked fine before we upgraded to GW8

platform is NW 6.5 sp8, gw8.02
