XADM: Content Conversion Errors with Large Recipient Lists

• Microsoft Exchange Server, versions 4.0 and 5.0

SYMPTOMS

When you attempt to send a message to a large private distribution list, event logs indicate content conversion errors (Event ID 210) and you may receive a non-delivery report (NDR).

CAUSE

The Windows NT OLE wrappers used for content conversion inside the message transfer agent (MTA) are not scalable enough for the large number of recipients.
