M365 Developer E5 Sandbox provisioning failed despite active Visual Studio Enterprise subscription

Hi everyone,

I'm looking for some help with an issue I'm facing while setting up a Microsoft 365 Developer E5 sandbox.

I have an active Visual Studio Enterprise subscription (valid until 2029), and it is successfully linked to my Microsoft 365 Developer Program account.

What happened

1. I joined the Microsoft 365 Developer Program.
2. I selected Instant Sandbox.
3. I entered the required information and selected my Visual Studio Enterprise subscription.
4. The portal initially displayed the following message:

   "It's taking longer than expected. Your setup is being processed. There is no action required from you at this time."

5. After waiting for nearly 24 hours, the dashboard changed to:

   "You don't currently qualify for a Microsoft 365 Developer Program sandbox subscription."

What I've verified

• Visual Studio Enterprise subscription is active and linked to my Developer Program account.
• A developer tenant appears to have been created.
• I can access the tenant through the Microsoft Entra Admin Center.
• An Azure subscription named similar to devProgram_... is visible.
• In the Microsoft 365 Admin Center (Billing → Your products), only Microsoft Entra ID Free is listed.
• No Microsoft 365 E5 Developer subscription was provisioned.
• No sample users or Microsoft 365 workloads (Exchange, Teams, SharePoint, etc.) appear to have been created.

My understanding

It appears that the developer tenant was created successfully, but the Microsoft 365 Developer E5 sandbox provisioning either failed or never completed. As a result, I don't have a usable Microsoft 365 developer environment for testing Declarative Agents and MCP integrations.

Has anyone experienced this before?

• Is there a way to retry the E5 provisioning without creating a new Developer Program account?
• Is there anything I can check on my side?
• Does this require intervention from the Microsoft Developer Program team?

Any guidance would be greatly appreciated.

Thank you!
