Reply to all format incorrect when replying to a message sent from Exchange to a GroupWise Distribution list

D101 error when replying to all on an email sent from Exchange user to GroupWise distribution list

ERROR: "Some addresses are undeliverable and have been crossed out.

Would you like to go to the address book to resolve them?" while sending reply to all message.

Sending message disregarding the above errors results in all user receive the message correctly

User names in To: field appear several times when selecting to reply to all

The issue appears to be cosmetic as the recipients do receive the mail correctly after dismissing the error message received in the client during the send.
