Restrict Guest access in a certain Team to a domain
When collaborating in a Team with certain people it would be nice if you could limit adding guests based on their domain. For example, I create a Team to collaborate with Contoso, I want to be able to add only people with the contoso.com domain. This will prevent accidental mixing up of different companies in a single Team.

This needs to happen asap.

Dear LORD, we have this already in SharePoint Online, being able to blacklist by domain individually by SharePoint site.
We need this exact same functionality in Teams/Groups!!!

I have been researching this and it may already be possible? Saw another forum say "access is managed in exchange and teams honours this setting" haven't tried though
I agree. It would be great if Teams will have "Restricted domains sharing" feature like SharePoint Online (https://docs.microsoft.com/en-us/sharepoint/restricted-domains-sharing).
We make a new team to prevent data contamination if collaboration partner is different. But we do not have any solution to prevent accidental user contamination in one team.

I agree at our university we have a school that decided to create a separate SharePoint tenant and therefore they are "external" to our tenant. But we want to be able to share content with them and ONLY them for some team sites - so we want to specify that only the domains associated with that school will be allowed, but not any other external domains. This is a major obstacle for some of our departments that need to restrict access to research, medical records, etc.
