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?

I know it's part of Outlook nick name (NK2) file. But it has to be resolved
properly first by AD with proepr attributes.

Thanks.

The value within the brackets is whatever you put in there. It's just
part of the display name. At some time you've changed something --
either the samAccountname or the mailNickname (or both) and never
bothered to change the "TRISJ" in the displayName.

The entire legacyExchangeDN value would have to match, not just a
piece of it.

Change the value of the displayName property.

You'll be sad if you change the legacyExchangeDN value.

Apparently it IS found if you put TRISD into an address and then
"check names". If it wasn't Outlook would tell you it couldn't find
any match.

You can delete the .NK2 file and start over. Or ou can ask you
question in an Outlook forum since the address resolution is managed
by Outlook not Exchange.
