Active Directory Connectors cannot replicate a distribution list, and event ID 8270 is logged in Exchange 2003

In a Microsoft Exchange Server 2003 organization, Active Directory Connectors (ADCs) cannot replicate a distribution list if the following conditions are true:

• The alias name of the distribution list starts with a space.
• The alias name of the distribution list starts with an asterisk (*) that is followed by a space.
• The alias name of the distribution list contains 15 or more characters.
• Another distribution list that has a similar alias name has been replicated already in Active Directory. This occurs when the first 14 characters of the alias names are the same for the two distribution lists.

Additionally, the following event is logged in the Application log:
