Unable to add guest user in Shared Channel
The cross-tenant access settings is for Shared channels between two Azure AD orgs and both orgs need to configure their respective Azure AD cross-tenant settings allow shared channels to work. The information in the cross-tenant access settings page in Azure AD says non-Azure AD orgs use the collaboration settings.
I have not tried inviting non-Azure domains to a shared channel yet, but I did read in a couple blogs that shared channels only support Azure AD domains at the moment.
DWFL1 To add, as well as setting the Cross Tenant Access Policy on both sides. you also need to have the Team/Channel Policy allowing the remote tenants users to be invited to external teams. It should be by default, but I had been messing and it caught me out.
Also if you have Sensitivity Labels applied to Teams that prevent sharing Teams with external users that will remove the option to choose anyone outside your tenant.
StevenC365 DWFL1 It's still not working... When you say setting the Cross Tenant Access Policy on both sides, does that mean the guest hast to be within an Azure tenant? What about adding a guest from a gmail? Do they needed to be added as a guest in AAD first? I tried this and still no luck.
Also, all the Teams settings look right, no sensitivity labels.
