Adding External Users to a Shared Channel

Question

I am trying to add external users to a shared channel and when I type in their email address, I just get "We couldn't find any matches. Make sure the email address is correct." I do have the ability to add external users to shared channels turned on in the Teams admin area. Is there a licensing barrier to doing this on the invited users' side?

Hi @Anna Ploghoft

Yes, as you said, Teams guest cannot invite to the shared channel. For the outside organization users, you can allow your users to invite people from other organizations to use shared resources - such as shared channels in Teams - by default.

To allow users to invite B2B direct connect participants by default(Note that the organizations you collaborate with will also have to configure their B2B direct connect settings.)

1. Sign in to Microsoft Entra ID using a Global Administrator or Security Administrator account.
2. Expand External Identities, and then select Cross-tenant access settings.
3. On the Default settings tab, under Inbound access settings, select Edit inbound defaults.
4. Select the B2B direct connect tab.
5. On the Users and groups tab, under Access status, choose Allow access.
6. On the External applications tab, under Access status, choose Allow access.
7. Select Save.
