SYMPTOMS
When a user on an Exchange 2000 or Microsoft Exchange Server 5.5 computer sends an e-mail message that is addressed to a distribution list that contains all the users on the Lotus Notes Domino Server 5 and the Exchange 2000 server, the Exchange user may receive an non-delivery report (NDR) similar to the following:

From: System Administrator

Sent: Wednesday, November 1, 2001 8:14 AM

Subject: Undeliverable: Test message

Your message did not reach some or all of the intended recipients.

Subject: Test message

Sent: 11/1/01 8:14 AM

The following recipient(s) could not be reached:

User1, Test on 11/1/01 8:14 AM

Unable to deliver the message due to the number of specified recipients of the message

Too many recipients

NOTE: Each Lotus Notes recipient in the distribution list To field is listed in the NDR.

Additionally, the following event may be in the Application log on the Exchange 2000 server or the Exchange Server 5.5 computer:

Event ID 41300

Source: MSExchangeNotes Category: Exchange to Notes Description: Lotus Notes has a 32K limit in the To: field



CAUSE
This behavior is caused by a limitation on the Lotus Domino server. Earlier versions of Lotus Notes have a 15-kilobyte (KB) limit.



WORKAROUND
To work around this problem:
 * 1) Synchronize the directories between Exchange and Lotus Notes through directory synchronization (dirsync).
 * 2) The Lotus Notes group will appear as a mail-enabled contact.
 * 3) Add the contact for the Lotus Notes group to an appropriate distribution group in Active Directory.



STATUS
Microsoft has confirmed that this is a problem in the Microsoft products that are listed at the beginning of this article.



MORE INFORMATION
For more information about synchronizing directories between Exchange 2000 and Lotus Notes,
 * 1) In Exchange System Manager, open the properties of the Connector for Lotus Notes, and then click the Dirsync Options tab.
 * 2) Click the Help button (or press the F1 key on your keyboard) to open the context-sensitive help.

Microsoft continues to update the tools that support interoperability among Lotus Domino R5 and Lotus Domino 6, Microsoft Exchange Server 2003, and Microsoft Windows Server 2003 Active Directory. The updated tools for Lotus Domino replace the following tools that are included with Exchange Server 2003 and with Microsoft Exchange Server 2003 Service Pack 2:
 * Exchange Connector for Lotus Notes
 * Calendar Connector for Lotus Notes
 * Migration Wizard for Lotus Notes

To obtain these tools and to obtain guidance and additional resources, visit the following Microsoft Web site:

These updated tools provide additional functionality and address several issues that customers reported with earlier versions of the tools.
