New domain & email. How to set up forwarding from old domain email without buy two licenses

[molliemollie]

So we have just rebranded and have set up a new website i2r.com.au

We want the emails to now follow suit me@i2r.com.au for example.

Since this is a rebrand, we want the new emails to take the place of the old (Old example being: me@myi2r.com) 
What is the best way to make this happen without buying double exchange licenses for each person, since the one user is going to be using them and we already have them. - and buying 2 licenses for each person in the company is going to get expensive!

Is there a way to add me@i2r.com.au to outlook and just have me@myi2r.com forward to it, or something like that?

Add and verify the new domain to your O365 tenant, then add a primary/secondary email alias to each user that needs it. No additional licenses are needed.
