SYMPTOMS
You can send e-mail messages to a Lotus Notes client, but you cannot reply to e-mail messages that are sent from the Lotus Notes client. When you do so, you receive the following non-delivery report (NDR):
CAUSE
This problem may occur if all the following conditions are true:
- You are a user on a Microsoft Exchange Server 5.5 site.
- The Exchange Server computer in the site is connected by an X.400 Connector to an Exchange 2000 computer in a mixed-mode site.
- The Exchange 2000 computer in the mixed-mode site was upgraded from Exchange Server.
- The Microsoft Exchange Connector for Lotus Notes is installed on the Exchange 2000 computer in the mixed-mode site.
In this situation, Exchange 2000 uses an X.400 domain-defined attribute (DDA)-encapsulated address instead of the X.400 proxy address for the recipient.
