B2B Collaboration settings

Hello, I tried to set a B2B collaboration for Teams with a Chinese tenant, so we could sign-in in the rooms and do not appear as guest. First we added the tenant in Cross cloud meetings setting (both from each end). I also tick the "microsoft azure china". It didn't work and we still have the error message saying "access is blocked by the organization" User's image

User's image

So from both side, we changed the external identities in Entra console. We added the tenant ID in "organizational settings" but with no success. If someone has a previous experience with that, could tell what we are doing wrong, it will be very helpful. My idea is : changing the settings in "B2B direct connect" to allow inbound and outbound for external users from Chinese tenant ID. Is this enough to let external users sign-in? Thanks.

    Hi @ABK

    Thank you for posting this in Microsoft Q&A.

    I understand you are trying to set up a B2B collaboration for Teams with a Chinese tenant, but you are receiving an error message saying, "access is blocked by the organization."

    To set up B2B collaboration between partner organizations in different Microsoft Azure clouds, each partner mutually agrees to configure B2B collaboration with each other. In each organization, an admin completes the following steps:

    1.Configures your Microsoft cloud settings to enable collaboration with the partner's cloud. 2.Uses the partner's tenant ID to find and add the partner to your organizational settings. 3.Configures inbound and outbound settings for the partner organization. The admin can either apply the default settings or configure specific settings for the partner.

    After each organization completes these steps, Microsoft Entra B2B collaboration between the organizations is enabled.

    Based on you provided data it seems you have completed step1 and step2, you have to complete step3.

    Users from another Microsoft cloud must be invited using their user's principal name (UPN). Email as sign-in is not currently supported when collaborating with users from another Microsoft cloud.

    For more information, refer to this document: https://learn.microsoft.com/en-us/entra/external-id/cross-cloud-settings

    Hope this helps. Do let us know if you any further queries.

    Thanks,

    Navya.

    Hi @ABK

    I completely agree with the solution given by Navya, but please note: B2B direct connect is not supported for collaboration with Microsoft Entra tenants in a different Microsoft cloud.

    The following scenarios are supported when collaborating with an organization from a different Microsoft cloud: 1.Use B2B collaboration to invite a user in the partner tenant to access resources in your organization, including web line-of-business apps, SaaS apps, and SharePoint Online sites, documents, and files.

    2.Use B2B collaboration to share Power BI content to a user in the partner tenant.

    3.Apply Conditional Access policies to the B2B collaboration user and opt to trust multifactor authentication or device claims (compliant claims and Microsoft Entra hybrid joined claims) from the user’s home tenant.
