Dear all, Sorry I lost 3 days emails, anyone who had the answer please resend to me. I installed Exchange 2003 SP2 in Win2003 sp1, all are English version, but when I sent a wrong address and then got a system returned message, some information is Chinese, I would like them to be all English, How could I reach this target? In server, Control Panel->Regional Settings->Location, I set it as "China", is it the reason? Any help would be appreciated! -- Jobsz
