Hi andreg31,
I would like to confirm if you indicate OWA layout(mail.office365.com and www.outlook.com) or Office 365 portal layout. As far as I know, Office 365 after upgrade is being scheduled and you will see the new UI layout in Office 365 after upgrade. You can refer to http://community.office365.com/en-us/wikis/upgrade/guide-to-the-office-365-service-upgrade-for-2013.aspx
If you just would like to see the same UI both in outlook.com and Office 365 side, it is not available now. If you want to migrate to outlook.com, you need to cancel your verified domain in Office 365, and add custom domain at domain.live.com.
Thanks,
Johnny Zhang
