As a partner managing lot’s of tenants in Office 365,  it could prove useful to have a full list of these tenants and their subscriptions.

As always,  you first need to connect to your own Office 365 tenant in PowerShell. A great tutorial can be found here.

Snippet

Connected? Splendid.

This snippet runs a query with the Get-MsolPartnerContract cmdlet. It returns all contracts, delegated to you as a partner. The function then lists all subscriptions, amount of licenses and the status of these licenses.

function Get-TenantSubscriptions {
Get-MsolPartnerContract | foreach {
$tenant_id = $_.tenantid.guid
$tenant_name = $_.name
Get-MsolSubscription -TenantId $tenant_id | select @{Expression={$tenant_name};Label="Tenant name"}, skupartnumber, status, nextlifecycledate, totallicenses
}
}

Of course be careful with these kind of commands. Actions performed in bulk, on all of your customers, could have great consequences.

Cheers.
