We got several problems with Teams. First, we cannot use our own e-mail address to invite team members and or guests. EVEN WORSE: the standard microsoft address is REJECTED by ALL recipients! it's like email@example.com. This is horrible, I now need to copy the meeting item from either my calendar or Teams app, then past it in my own business e-mail and select all the team members' e-mail addresses.
How do I use my business e-mail address in Teams?? We've already changed the DNS records and our domain has been approved.
