There are literally thousands of different search criteria that we could specify for our users, but for this example we are going to create a custom search. In order to do that I select the Advanced Tab, and I should see something like you see here:
In this case, I have already filled in the properties that I want to use for my Address list. In this case, I only want the address list to display users who have a their City attribute set to Tampa. If you want to see what the actual LDAP Filter looks like, take a look at this figure:
Probably not something that you want to be writing from scratch every day, but keep in mind that with Exchange 2000, you do have the ability to actually write your own LDAP Filters should you need to do so. In my case I will always try to keep things simple, so I was able to meet my needs by simply using the Advanced Features capability. Now if you look at the bottom right hand side of the graphic from Figure 8, you will notice a Preview button. By clicking on that I will request that Exchange actually run that Filter against all the objects in my Exchange Organization, and return only objects that meet the specified criteria. Again, if you refer back to the Filter in the figure below, you will notice that amongst other things I am only looking for user objects. So I should only see user objects returned in my Address List. Figure 9 verifies this for me.
