Multitenant organization (MTO): user licenses

Hello everyone,

 

As described https://learn.microsoft.com/en-us/microsoft-365/enterprise/set-up-multi-tenant-org, I have created an MTO. It seems to have worked because I can see users from tenant A in tenant B. Everything looks correct, as the users have #EXT# in their usernames, their type is “Member”, and their identity is “ExternalAzureAD”. BUT they are all unlicensed.

 

My question: is there a way to synchronize the licenses of the users, or do I really have to purchase the same license twice for a single user?

 

Specifically, I am interested in the following licenses:

  • Microsoft 365 Business Premium (access to Teams, SharePoint, Exchange Online shared mailboxes, etc.)
  • Dynamics 365 licenses (e.g., Business Central).

 

Thank you very much for your assistance, and warm regards,
Nico

  • We have a similar situation where we must temporarily assign a PowerApps license to provision users in our MTO sub-tenant. Removing the license after provisioning still allows them access, which feels counterintuitive. We are taking about more that 50k users setup. All are cross tenant users are member of the subtenant.

  • You cannot "share" licenses between tenants. If you have a need to assign a license to a cross-tenant synced user in the resource tenant, you will have to expend one of the available licenses therein.
    If this is some sort of a tenant-to-tenant migration scenario, you can contact Microsoft to help with transferring licenses between the two tenants.

      VasilMichev if this is true, then MTO makes absolutely zero sense. 

       

      For a minor benefit of "kinda slightly better" integration, you now have to effectively double your license count and cost, for both tenants.
