As an indirect CSP partner, we can list all our client tenants and then run tasks for these tenants using the old MSOnline PowerShell module by adding the -TenantId argument to each cmdlet. It seems this is no longer possible with the new Microsoft Graph API and cmdlets.
# MSOnline will return results from client tenant Get-MsolSubscription -TenantId <client id> # MS Graph will only return results from our own partner tenant Get-MgSubscribedSku ??
Will this functionality be made available to bring these modules up to feature parity? At this time we can not replace the MSOnline module with the MS Graph Powershell SDK.
