Microsoft Exchange Server provides a foundation for shared address lists through the global address list; enter outside addresses as custom recipients. If everyone is using Microsoft Outlook, you can also create public folders for sharing contacts.
If you don't have Exchange Server, beyond the tools listed below, you might consider using:
- An LDAP server -- especially if you have a Windows 2000 server running Active Directory, which is Outlook can access with its LDAP service. See Shared address book with Active Directory.
- Net Folders (Outlook 98 and Outlook 2000 only and not fully reliable)
- A web-based contact list with a synchronization feature
- Using the Briefcase to Share Microsoft Outlook Folders
As noted above, for Exchange Server users, the Global Address List or a public Contacts folder provide a built-in means for Exchange Server users to tap into a shared address list. These tools can take it one step further by synchronizing the GAL or a Contacts folder with other contact databases or synchronizing user Contacts folders with a public folder.

Priasoft provides a solution for pre-staging objects and synchronizing address book attributes between two or more Exchange environments. The CS (Collaboration Suite) helps with co-existence migration plans and can also be used to migrate and synchronize Distribution Lists and their members between environments.

As you know, Exchange online limits the number of recipients (both internal and external) per message for each mailbox. There is no way to limit the number of distribution lists a certain group of people can send to. If you run Outlook OWA or Outlook 365 on Windows or Outlook on Mac, RestrictDLs add-in will solve this problem.
