Create a Mail Contact for the Shipfix Address
Before configuring forwarding, you need to create a mail contact in Exchange Online for the Shipfix virtual mailbox address. This allows Exchange to recognize the Shipfix address as a valid forwarding target.
In the Exchange Admin Center, go to Recipients > Contacts
Click Add a mail contact
Fill in the required information: enter the Shipfix forwarding address as the External email address
Add the forward header
Click Next, then Next again, and click Create to create the contact
Enable Forwarding on the Mailbox
In the Exchange Admin Center, go to Recipients > Mailboxes
Search for and click on the mailbox you want to configure forwarding for
In the mailbox details panel, under Mailbox > Email forwarding, click Manage email forwarding
Toggle Forward all emails sent to this mailbox to ON
In the Forwarding address field, search for and select the mail contact you created in the previous step
Check the box for Deliver message to both forwarding address and mailbox to keep a copy of the forwarded email in the original mailbox
Click Save
N.b. If your Exchange Online doesn't allow external forwarding, you need to go to the Anti-Spam Security Portal and set Automatic Forwarding Rules to "On".
