Outlook / Exchange – Shows up 2 different name in To- field

Hey,

Im having problems with some of my “Auto Completation” in Outlook (2003). Running Exchange 2007.

For example,
I have a user account called Test1 (John Karlsson). I change this account some.

The account is still called “Test1” but I change name to “Bob Testing”. Everythings fine.

Somehow, some of these users ends up with strange behaviour in Outlook.

When I try to send a mail to “Bob Testing” press CTRL+K and Outlook Auto Completes the name. Fine.

I start a New Mail and type Bob Testing. Now, to the problem. It all ends up showing my
name user and some of my old user.

For example

Bob Testing

Im pretty sure this must be Server-side related, but not to sure how or where to solve it.

Anyone?

Thanks!

Br,
John
