I was asked why when someone sets up an email forward from one user to another in Exchange Management Console, the original user does not get a copy and there is no option to “Deliver message to both forwarding address and mailbox”.
After a quick google I found a suggestion to use the Set-Mailbox -Identity “mailbox” -DeliverToMailboxandForward $true -ForwardingSMTPAddress “firstname.lastname@example.org” in the exchange Management Shell.
Apparently the “Deliver message to both forwarding address and mailbox ” is not available in the Exchange Management Console for Exchange 2013 and you have to use the Exchange Management Shell.
I tried this but got a strange message saying nothing had changed.
“WARNING: The command completed successfully but no setting of “mailbox” have been modified.”
After further investigation I found I should be using -ForwardingAddress not -ForwardingSMTPaddress for internal users.
So the command you need to forward email to an internal address is :
Set-Mailbox -Identity “mailbox” -DeliverToMailboxandForward $true -ForwardingAddress “email@example.com”
If this helps please let me let me know and if there’s a better way then definitely let me know !
