We have an MS Exchange server and a Lotus Notes (Domino) server in the same domain. When mails are sent from Exchange to LN and vice versa, using the standard mail addressing the Exchange connector for Lotus Notes seems to work like a charm.
So, when a LN user sends a message to an Exchange user with other LN users addresses in the CC: field, then all the addressed users get the message correctly (whether the message passes the connector or not). BUT.. When the Exchange user whishes to ReplyToAll, then the messages for the LN-users that were in the cc:-field bounce (btw, exchange addresses are delivered correctly because they do not pass the connector, evidently). The cc: LN addresses (that appear in the received message as <username>/<originating mail domain>@<destination> are not or incorrectly converted by the connector.
What is causing this, and more important, how to solve it.
Thanks for your advice.
