There are different ways to connect teams through Microsoft Teams. We use B2B direct connect as it’s the most user-friendly and secure method, utilizing 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, langdock.com should be on the whitelist. If you use a blacklist, it should not be on the blacklist.

Create a Microsoft Entra ID B2B direct connect channel

You will need an admin with Microsoft Security permissions to set up the following steps. We follow the steps detailed in this Microsoft guide. The guide from Microsoft goes through these steps:
  • Add an organization.
  • Configure inbound settings for the organization to allow users from the organization to be invited to your shared channels.
  • Configure outbound settings for the organization to allow your users to be invited to the other organization’s shared channels.
We will only add an organization and configure outbound settings. Inbound settings are not needed since the Langdock team will invite you to a shared channel.

  2. Ensure that Teams and Skype for Business users in external organizations is either set to Allow all external domains or Allow only specific external domains
