Outlook: Hiding DL Members

How can I set up a distribution list (DL) with Exchange 2000 Server and Outlook so that recipients can see only the name of the list in the To box and not the names of the list members?

The DLs that Outlook creates in contacts folders don't hide their membership. The solution is to use the Microsoft Management Console (MMC) Active Directory Users and Computers snap-in to create an Active Directory (AD) distribution group and set its properties. To set the group's properties, you'll need appropriate permission to access the organizational unit (OU) in which you want to create the distribution group. To set the group's properties, follow these steps:

  1. In the selected OU, choose Action, New, Group. In the New Object - Group dialog box, give the group a name, and set the Group type to Distribution. Microsoft also recommends that you set the Group scope to Universal to avoid replication problems between Exchange and Global Catalog (GC) servers. Making the group a universal group means that you can use it in all domains in the forest. (If you want to use the distribution group to secure access to public folders and other data, you'll need to create a Universal Security Group—USG—instead of a distribution group.) Click Next.
  2. In the next dialog box, select the Create an Exchange e-mail address check box. Check Next, then click Finish.
  3. In the Users container, bring up the properties of the newly created DL, and add members on the Members tab.
  4. Switch to the Security tab, then click Advanced. Under Permission Entries, select Authenticated Users, then click View/Edit.
  5. On the DL's Permission Entry dialog box, switch to the Properties tab, which Figure 1, page 6, shows. Under the Permissions list, change the permission for the Read Members property from Allow to Deny. Click OK until you return to the snap-in.
