SKU, quota and policy restrictions on Azure for Students and Free Subscriptions

Hi CvWyk​, going direct to your questions

 and for your students, here's a list to make things easier

Azure for Students VM Troubleshooting Checklist

Quick Student Guide

Use this checklist when your Azure VM deployment fails.

Step 1 — Confirm You Are Using an Allowed Region

Your student subscription only works in certain Azure regions.

Check allowed regions:

1. Open Azure Portal
2. Search for Policy
3. Go to:
• Authoring → Assignments
4. Open:
• Allowed resource deployment regions
5. Write down your allowed regions

Only deploy VMs in those regions.

Step 2 — Try Another Allowed Region

Even allowed regions may fail temporarily due to Azure capacity shortages.

If deployment fails:

• Try another allowed region
• Test several approved regions

 Some students only succeed after changing regions multiple times.

Step 3 — Use Recommended VM Sizes

Some older VM sizes are restricted or retired.

Recommended VM sizes:

• Standard_B2ats_v2
• Standard_B2ts_v2
• Standard_B2als_v2

Avoid:

• B1s
• older B-series VM sizes

Step 4 — Do NOT Select Availability Zones

Availability Zones can block VM creation on student subscriptions.

Best practice:

• Leave zone selection on default
• Use:
• “No infrastructure redundancy required”

This avoids:

• “Unsupported availability zone”
• “SKU unavailable in selected zone”

Step 5 — Check VM Quotas

You may hit VM quota limits even with free credit available.

Check quotas:

1. Go to:
• Subscriptions → Usage + quotas
2. Look for:
• Total Regional vCPU quota
• VM family quotas

Common error:

• “Total Regional Core quota exceeded”

Step 6 — If No VM Sizes Appear

Possible causes:

• region capacity exhausted
• restricted subscription
• unsupported VM family
• temporary Azure capacity issue

Try:

Another allowed region
Another Bsv2 VM size
Removing Availability Zones
Trying again later

Step 7 — Use CLI to Check Available VM Sizes (Advanced)

The Azure Portal sometimes shows incomplete information.

Azure CLI command:

Shell

az vm list-skus \

--location <region> \

--resource-type virtualMachines \

--output table

Show more lines

Example:

Shell

az vm list-skus \

--location denmarkeast \

--size Standard_B \

--all

``

Show more lines

This shows which VM sizes are actually available for your subscription

Step 8 — Still Not Working?

Document the following before asking for help:

Subscription type
Region used
VM size attempted
Exact error message
Screenshot of:

• Allowed regions
• Usage + quotas page

This makes troubleshooting much faster.

Recommended “Safe” Student Deployment Setup

Important Reality Check

Azure for Students subscriptions can behave differently between students because:

• allowed regions differ
• VM capacity changes dynamically
• some VM sizes are restricted
• region availability is not always consistent

A deployment that works for one student may fail for another student with the same subscription type.
