How to add an alias from a different domain to office365 so a user can change the 'from' to match

I have a client with an office365 account with a single e-mail address 'user@hisdomain.com'. This user does outside sales work for other companies that have their own e-mail systems and domain names, and they have created e-mail addresses for my client in their domains 'user@theirdomain1.com and user@theirdomain2.com'.
My client uses office365 OWA, Outlook and Outlook for Mobile to access email
We currently have forwarded 'user@theirdomain1.com to user@hisdomain.com'. When my client receives an e-mail from 'user@theirdomain1.com' they want to be able to reply to the e-mail and change the 'from' address to 'user@theirdomain1.com'
How can I set this up in office 365 so they are able to change the 'from' address to the proper Domain for the reply to keep e-mail continuity?
Thank you

will the connected accounts pull in real time, or does the OWA need to be opened? I assume nothing these days:)

also, can you elaborate on "You can however add his "other company" email as additional account in Outlook, which will allow him to pick up the address when composing messages." . Simple rundown/article if you have something for me to reference. Thanks!

Not in real time, it's once every 30 mins or so. For the second question I simply meant to add the other company's mailbox in Outlook.
