- Microsoft Exchange 2000 Enterprise Server
- Microsoft Exchange 2000 Server Standard Edition
SYMPTOMS
E-mail messages that are sent to users and distribution groups are delivered in duplicate.
CAUSE
This problem may occur if both of the following conditions are true:
- The e-mail message is addressed to a distribution group and to a recipient who is a member of that distribution group
- The message is addressed to a distribution group that is expanded externally (beyond its own routing group). For example, the message is sent from a Microsoft Exchange 2000 Server mailbox to a distribution group that is expanded to an organization that is using Microsoft Exchange Server 5.5.
This problem may also occur if the original message requires content conversion. For example, the problem may occur if the local recipient has their default message format set to the Rich Text Format (RTF) but the distribution group has its default message format set to plain text.
