XP with Outlook 2003 SP3 and Exchange 2003 SP2. A user's login ID is TRISD
and it's the same as his Exchange alias. When he typed in TRISD in cc: and
click on Check Name it was resolved. Next time when he typed TRIS it
resolved his name automatically as Trisna, David TRISJ. But if typed as
TRISD nothing get resolved automatically till click Check Name. Using ADSI I
found TRISJ is a value of his LegacyExchangeDN.

Here are my questions:
1. should the name within be from Alias or LegacyExchangeDN attribute?
Looks like it's from LegacyExchangeDN since his alias is TRISD.

2. my user wants to get his name resolved when typed TRISD and show
Trisna, David TRISD not TRISJ, what should I do? Modify LegacyExchangeDN
attribute? What nenative impact will be by doing this?

Thanks.
