Shared Teams Channel

There are different ways to connect different teams through Microsoft Teams. We use B2B direct connect as it is the most user-friendly way and the most secure way as it utilizes Entra and exchanging tenant IDs.

​

Required Permissions in Teams

1. Navigate to the Microsoft Teams Admin Center.

2. Click `Global (Org-wide default)

3. Ensure that Join external shared channels is activated. If you changed your settings, click Apply

   Please verify that the langdock.com organization is not blocked. If you use a whitelist, this means that should be on the whitelist. If you use a blacklist, they should not be on the blacklist.

​

You will need an admin with Microsoft Security permissions to set up the following steps. We will follow the steps detailed in this guide.

The guide from Microsoft goes through these steps:

• Configure outbound settings for the organization to allow your users to be invited to the other organization’s shared channels.
