When sending emails to external recipients, in Exchange Online we have External Recipients Tips Enabled so users recognize that the emails going outside the org.
With Microsoft Teams, email addresses are created as *.email@example.com or *.firstname.lastname@example.org. I believe these addresses cannot be changed to match one of our own domain names.
The following recipient is outside your organization: *.email@example.com
Is there a way to exclude those two domains from getting marked as external so the users aren't displayed the notification and aren't worried about the messages going outside the org. when they are told that they are staying within the org?
