XCON: Exchange Notes Connector Service Stops and Causes Message Backlog in the Exchange Notes Connector (298486)
The information in this article applies to:

- Microsoft Exchange Server 5.5 SP4
This article was previously published under Q298486 SYMPTOMS
If a message that contains more than 1,024 attachments is submitted to the Exchange.box on a Lotus Notes server, the Microsoft Exchange Connector for Lotus Notes service (Lsntsmex.exe) may stop. Messages may sit in the queue and may not be delivered. The Exchange Notes Connector does not mark the message that contains more than 1,024 attachments as a problem message, but no new mail is processed until you remove the message and you restart the service.
CAUSE
This problem can occur because the Exchange Server information store cannot process more than 1,024 attachments for each message; therefore, when the connector tries to create the 1,024th (0x400th) attachment, the information store stops responding. The connector calls fail, and the Lsntsmex.exe process stops, which causes subsequent messages from Notes to Exchange Server to be backlogged.
