User experience with Multi-Domain single Tenant.
Matt Suderman Hello Matt, If I understand correctly, you will only have one tenant with 2 custom domains representing each company, right? The experience in Teams will be seamless - each user will be able to communicate with each other across companies, with no silos.
The login experience for users will depend on the UPN selected, but from a user perspective it will function like a single Teams environment. The custom domains are basically for login, email routing in/out, etc. But users will not notice divisions between companies in Teams.
Thanks for the reply. Just a small followup question.
So, the way you describe it,
- It will function like a single environment (from a user perspective)
- the domains are basically for login and email in/out.
Do I have it right?
Matt Suderman Hello Matt, yes, the way I also understood your scenario 
It'll be like that
