Hello,
Exchange 2010 Edge Server properly SP'ed and Patched: EDGE01
Exchange 2013 Primary Mailbox Server: MB01
Exchange 2013 Archive Mailbox Server: ARCHMB01
Mailflow from the EDGE01 to MB01 appear to be working just fine. In some instances it appears that the edge server is trying to deliver messages to the Archive Mailbiox server, ARCHMB01. WHen this occures, external senders are reciveing the following undeliverable message:
Your message wasn't delivered due to a permission or security issue. It may have been rejected by a moderator, the address may only accept e-mail from certain senders, or another restriction may be preventing delivery.
The following organization rejected your message: ARCHMB01.xxx.xxx.com.
ARCHMB01.xxx.xxx.com #<ARCHMB01.xxx.xxx.com #5.7.1 smtp;530 5.7.1 Client was not authenticated> #SMTP#
Security settings on the recieve connectors for the ARCHMB01 match MB01. Edge Subscription was done on the primary mailbox server, MB01. Does the Edge Subscription need to also be completed on the Archive Mailbox server since it also holds the transport role?
Any thoughts on this mail flow issue is appreciated.
Thank You
