SYMPTOMS
Lotus Notes users may receive a non-delivery report (NDR) when replying to an e-mail message originating from Exchange Server. This NDR might result from recent changes made on the Exchange Server, particularly to the Notes proxy address of the Exchange Server user.



CAUSE
The Exchange Notes Connector does not know how to handle extra spaces in the Notes proxy address of Exchange Server users. This might be a result of modifying the Notes proxy address generation rule under Site Addressing to a format that might generate a space.

For example:

&g &i &s/Site/Org@Exchange)

A user that did not have a middle initial would contain a Notes proxy address of similar to the following:

"John Smith/Site/Org@Exchange"

Note the extra space between John and Smith.



RESOLUTION
To resolve this problem, obtain the latest service pack for Exchange Server version 5.5. For additional information, click the following article number to view the article in the Microsoft Knowledge Base:

191014 XGEN: How to Obtain the latest Exchange Server 5.5 Service Pack

The English version of this fix should have the following file attributes or later:

Component: Notes Mail Connector



WORKAROUND
To work around this problem, specify a Notes proxy address generator rule that does not result in any addresses with an extra space. Administrators can also manually correct the user's Notes proxy address by removing the extra space.



STATUS
Microsoft has confirmed that this is a problem in Microsoft Exchange Server version 5.5.. This problem was first corrected in Exchange Server 5.5 Service Pack 3.



MORE INFORMATION
This issue might still be a problem if modifications to the Notes proxy address were accomplished through some other mechanism, such as importing/exporting CSV files, or through a dirsync mapping rule. Microsoft is aware of this problem.
