How to collaborate with external participants in a shared channel?
+
You can share a team channel with external users either by directly adding them through their email addresses or by sending an invitation to a team owner of the external organization. Once the team owner accepts the invitation, users can access your channel directly without switching tenants.
Before adding external users to shared channels, it is mandatory to configure all the settings below so that they can access the content shared via these channels.
- Login to the Microsoft 365 admin center. Navigate to Settings»Org settings.
- Under the Services section, select Microsoft 365 Groups and verify if both options allowing group owners to add external users and permitting guests to access your group's content are enabled.
Login to the SharePoint Online admin center . Under Policies, select Sharing. Set the external sharing level to "New and existing guests".
- Login to the Microsoft Entra admin center. Navigate to Identity»External Identities»Cross-tenant access settings.
- Under the Organizational settings section, click on +Add organization. Enter the domain name of the desired organization and hit Add.
- Configure inbound access settings by selecting the "Inherited from default" link. Under the B2B direct connect tab, choose Customize settings. Then, tap "Allow access" and "All external users and groups" options.
- Under the Applications section, choose "Allow access" and "All applications". Click Save.
Note: Your partner organization must configure outbound access settings so their users can access your shared channels.
After configuring all the above settings, you can share Teams channels with external users or send an invite to their team owners.
- Here, you can find all the external users in shared channels along with the team's name, channel name, and their domain.
- Pro Tip: Apply the "Channel Name" easy filter to identify external users within specific shared channels designed for collaborative work on a crucial project.
