Microsoft Teams is a great collaboration tool. Collaboration means sharing everything with all the members of your Team.

In many scenarios I have been asked to provide a private Channel and library for some of the Team members.

Private Channels are not available at the moment. It’s a feature that is being requested in the Microsoft Teams User Voice. https://microsoftteams.uservoice.com/forums/555103-public/suggestions/16911079-support-for-private-channels

In this article you will find the steps to create a private/secured document library in Microsoft Team.

You should already know that documents stored in Microsoft Teams are actually stored in an associated SharePoint site.

Here are the steps to create a tab to display private/secured documents on a Microsoft Team Channel

  • Access your SharePoint site from Microsoft Teams
  • Create a new SharePoint group
  • Add member to the new SharePoint Security group
  • Create a new Document library in the SharePoint site
  • Break permission inheritance on the document library
  • Remove permission to Visitors and Members group on the document library
  • Grant permission to the new SharePoint group on the document library
  • Add a new tab to the document library on your Team’s channel
  • Test to confirm that it works

1.  Access your SharePoint site from Microsoft Teams

  • Open your Microsoft Teams client

  • Click on Stop Inheriting Permissions (on the ribbon)
  • Click OK to accept the changes

6.  Remove permission to Visitors and Members group on the document library

  • Still in your permission settings

  • Click on Remove User Permissions (on the ribbon)
  • Click OK to accept the changes

7.  Grant permission to the new SharePoint group on the document library

  • Click Share

8.  Add a new tab to the document library on your Team’s channel

  • Open your Microsoft Teams client
  • Click on your team
  • Click on the channel where you want to add the secured document library
  • Click on the plus (+) sign

  • Click on Use a SharePoint link
  • Type the URL of your SharePoint Site
  • Click GO
  • Select your secured document library

  • Click on the Secured document library Tabs
  • You should have a message that says : You don’t have access to these files
