Exchange User's "legacyExchangeDN" Value Displays Instead of Name

silver1386 asked
We are running Exchange 2007 on a Windows Server 2008 server.  I have a user whose name seems to display incorrectly sometimes.  It seems to only happen on calendar appointments that he creates (when it tells who the owner of the appointment is).  It does not happen if he is just an invitee of an appointment or in emails.  What appears instead of his name is (we think) his legacyExchangeDN value.  I believe that's what it's called; either that or X.500 Address.  The string is "/o=Example/ou=Exchange Administrative Group (FYDIBOHF23SPDLT)/cn=Recipients/cn=juser".

I went back through my documentation on how I set up his account.  The only thing that I see is different has to do with the Alias.  On setting up the account, the default Alias is the user's username.  I typically change that during the setup process to "first.last".  But I forgot, and I had to go back and change it later.  Now, both aliases show up as email addresses in his E-Mail Addresses tab.  I wouldn't THINK that this would make a difference.  Any thoughts?

please don't select all users just select the user juser I did a typo


I don't understand what you're suggesting.  My knowledge of Exchange is very little.  I'm not sure what the admodify tool is, either.

go to the admodify.codeplex.com and download it
from the tool select the user that has the problem, go to the custom tab and select modify attribute
the attribute name is proxyaddresses
and add the value
 x500:/o=Example/ou=Exchange Administrative Group (FYDIBOHF23SPDLT)/cn=Recipients/cn=juser

make sure to select multivalue append
