SBS 2011, Exchange 2010 - I have a mailbox "firstname.lastname@example.org" with the sole purpose of receiving email from an external website. The email should be forwarded to 3 internal recipients in my organization - so I have created a distribution list "email@example.com" with the 3 mailboxes as members. However, the email does not get forwarded to the recipients, but if I configure this mailbox to forward to a SINGLE internal recipient, it DOES get forwarded.
I have added both mailboxes to my spam filter so that does not appear to be the problem. In Exchange Management Console, under delivery options, I have the forwarding address on "firstname.lastname@example.org" checked and "Deliver message to both forwarding address and mailbox" checked.
I'm not sure what to look for in the message tracking logs for this, if this is the first suggestion for finding a fix.
