Unable to expand a distribution list in Outlook – Exchange 2003 Environment

Have you ever receive an error stating that “There was an error while expanding the list. The list was not fully expanded.” when you try and expand a distribution list in Outlook? The error looks like the one below:

list

To solve this change the list to a Universal Distribution Group. Wait for replication if need be and you will then be able to expand the list and view the members within Outlook.
