You could move all of the email from one of the mailboxes to the other and set it to also use the other email as an alias.

You can use the Export-Mailbox CMDLET in Exchange Management Shell to move all data from one to the other.

Check here for more info:

If not comfortable with CMDLETs, you can also download everything to a PST and then manually import it with the Outlook client.

Then as Joshua mentioned, you can then assign the SMTP address from the original mailbox to the new one.

Here is how to add an additional email addresses to a recipient

When you export the mailbox then import it to the other, all of the items should be accessible in OWA, just make sure to import them and not just open the PST file.

Assuming you are deleting the old mailbox then you would go to the new users properties under EMC >> Recipient Configuration >> Mailbox >> right click Properties >> Email Addresses tab >> Add button >> SMTP Address.

Correct. All mail from the old mailbox would be visible from all devices in the new mailbox.

No you cant have 2 users with the same email address unless it is a distribution group.

Are olddomain.com and newdomain.com both managed by the same exchange environment?

You could configure mail forwarding on the old user.
EMC >> Recipient Configuration >> Mailbox >> right click Properties >> Mail Flow Settings tab >> Delivery options >> check the Forward To: checkbox, select the new mailbox.

Optionally also check the "Deliver messages to both" checkbox if you want a copy of each new message in both places.

Yea, I would forward like Gareth suggests. Then you can export the entire john1@olddomain.com to pst and import it into the users mailbox.

Once you verify that sending and receiving work for the new address, then I would disable the forward and delete the old mailbox, add john1@olddomain.com as an additional email for john1@newdomain.com, and done.
