I'm just getting into Teams and I think it will work for us, but I noticed an issue. I manage IT for a family that owns three business all in the same building (mostly). So licensing & costs are often shared.
I set up some new teams and then today I was in Exchange (O365) and noticed all my email addresses are Cats104@Dogs.com. The 104 comes from duplicate groups I have created. So I think I can handle that. But I need the group emails to be Dogs@dogs.com
Cats own the Office 365 license. But I need the companies to appear different. Can I change these group email address names & domains?
