VM sizes show NotAvailableForSubscription

Good day,

It looks like there is a recent change on availability of Azure VM SKU for sponsored subscriptions. We were planning to deploy a few Bv2-series VMs in our newly obtained sponsored subscription and unfortunately were took by surprise that most of SKU (including Bv2-series) shows NotAvailableForSubscription in Canada Central.

However those SKUs are available in Pays-as-you-Go. Also I checked other sponsored subscription, it says the same: NotAvailableForSubscription.

I tried to search official communication or documentation about this updates, but failed to find.

Questions:

  1. Is there an official communication from Microsoft about this change?
  2. Is there a way to request availability of Bv2-series SKUs for our sponsored subscription?

Most posts and answers are recommending to check the quota, but in our case the quota is 0 out 65.

    Hello

    Based on the information and screenshots provided, the "NotAvailableForSubscription" message indicates that the requested VM SKU is currently unavailable for your specific subscription type. Since the same VM sizes appear to be available in Pay-As-You-Go subscriptions but not in Sponsored subscriptions, this points to a subscription-level SKU availability restriction rather than a quota issue.

    The fact that your quota shows available capacity (0 of 65 used) further suggests that quota is not the limiting factor in this scenario.

    To validate the restriction, you can run the following Azure CLI command:

    az vm list-skus --resource-type virtualMachines --all --query "[?name=='Standard_B2s'].{Name:name,Locations:locations,Restrictions:restrictions}" --output json

    If the output contains "ReasonCode": "NotAvailableForSubscription", it confirms that the VM size is currently unavailable for your subscription in the selected region.

    At this time, we are not aware of any publicly documented announcement regarding a recent change affecting Bsv2-series availability for Azure Sponsored subscriptions. VM SKU availability can vary based on factors such as subscription offer type, regional capacity, and platform policies.

    As a workaround, you may consider deploying the VM in a different Azure region or testing an alternative VM family that is available for your subscription.

    Thank you for the prompt response confirming the same. We checked before and we have an error code NotAvailableForSubscription.

    Our questions why a numerous quantity of SKU suddenly became unavailable for the sponsored subscriptions. Like I mentioned earlier, we successfully provisioned B-series and D-series Azure VMs in May 2026, but not able to do now.

    We would like to get in touch with Microsoft support to resolve this issue or get an official response why this may not be done.

    Thank you!
