How to specify the default Address List in OWA

By default, Microsoft Outlook Web Access shows all address lists in Active Directory, regardless of the permissions that are set on the address list. To restrict access so that users can only view the address lists that are contained in their own OU, you can configure the msExchQueryBaseDN attribute for the OWA user.

In an Active Directory environment with a large number of users where there is a need to filter the long list to just a number of relevant recipients, this is particularly useful.

Here’s how to go about it:

  1. Open ADSIEDIT
  2. Find the user for whom you want to restrict the view and open the properties
  3. Find the msExchQueryBaseDN attribute. Enter the DN for the OU or restricted Address list you want the user to see in OWA. To enable user to see all lists, just clear the field.

To find the DN for the restricted address list you created, open ADSIEDIT and navigate to Configuration > Services > Microsoft Exchange > [Organization Name] > Address Lists container. Here is an example:

CN=My Address List,CN=All Address Lists,CN=Address Lists Container,CN=Organization,CN=Microsoft Exchange,CN=Services,CN=Configuration,DC=MyDomain,DC=com

If you prefer to use the DN of an OU, it would look something like this:

OU=Department,OU=Division,DC=MyDomain,DC=com

If you want to edit msExchQueryBaseDN attribute for a large number of users (entire OU or domain), you can use the ADModify tool.
