Changing Teams privacy settings from Private to Public. What to expect?

When creating a Microsoft Teams team, you can choose Private, Public, or even Org-wide. For the purpose of this blog post, we’re going to talk about Private and Public teams.
 

Create a Private Team

So, I create a Teams, set it up as Private, and add only one member.

As we know, when creating a Microsoft Teams, a SharePoint site is automatically created as well, and the membership should reflect what’s in Teams. Meaning nobody else than those 2 users can access the Team, nor the SharePoint site.

Changing from Private to Public

Now let’s change our team’s privacy setting to make it Public… Navigate to your targeted Team –> ellipses –> “Edit team”

Did anything change?

At first glance, not really. But if we dig a bit deeper into the SharePoint site permissions, we now have an added entry for Everyone except external users!

So be careful when changing the Teams privacy settings, because Public means Public!
