Forwarding email from Exchange

[ATC]

I want to set up email forwarding for one or more users on my Exchange server but can't find an option for it.

Create a Custom recipient for the forwarding address. Set this address as the Alternate recipient of the mailbox (mailbox property – delivery options tab)whose incoming mails have to be forwarded. Also select if the mails are to be sent to both the recipients or only the Alternate recipient.
