Exchange Server 2003 users cannot reply to an e-mail message that was sent from Lotus Notes when the Lotus Notes user's e-mail address contains 8-bit ASCII characters

In a Microsoft Exchange Server 2003 and Lotus Notes coexisting environment, the directory information is synchronized between Exchange Server 2003 and Lotus Notes. A Lotus Notes user is synchronized as an Active Directory contact that can be checked by Exchange Server 2003 users who use the global address list (GAL). However, a Lotus Notes user's e-mail address may contain one or more 8-bit ASCII characters, such as a "ç," an "â," or an "ä." When the e-mail address contains such characters, Exchange Server 2003 users cannot resolve the Lotus Notes user's address to an Active Directory contact. Therefore, Exchange Server 2003 users cannot reply to these e-mail messages.

For example, assume that a Lotus Notes user's e-mail address is "düssel Köhler." When that user sends an e-mail message to Exchange Server 2003 users, the Exchange Server 2003 users find that the Lotus Notes sender's address is resolved to "dussel=3000Kohler." Additionally, if you check this Lotus Notes user in the Active Directory directory service, the user's address is displayed as "d=00FCssel=3000K=00F6hler."

To resolve this issue, install the latest version of the Microsoft Exchange Server 2003 Connector for Lotus Notes. To obtain the latest version of the Microsoft Exchange Server 2003 Connector for Lotus Notes, visit the following Microsoft Web site:
