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 Microsoft Teams
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 Teams, 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 MS Teams >> ellipses >> “Edit team”
From the drop-down menu, change from Private to Public, and click on “Done”
Did anything change?
Well, at first glance, not much 🤔
But if we dig a bit deeper into the SharePoint site permissions, we now have an added entry for Everyone except external users! 😮
🔓 If a user with the appropriate license(s) knows the URL of the SharePoint site, or the Teams, then he/she can access the resources & documents.
This user will be presented with the following:
And therefore, be a member of the associated SharePoint site.
So be careful when changing the Teams privacy settings, because Public means Public!
