Frequently Asked Questions

Why is the Microsoft 365 Developer sandbox option missing from my Visual Studio portal?

This can happen if your specific subscription tier does not include the benefit, if the benefit has already been claimed using a different account, or due to a temporary syncing delay in the Microsoft subscriber portal.

Is the Microsoft 365 E5 developer sandbox completely free with Visual Studio Professional?

Yes, qualifying active Visual Studio Professional subscriptions include a free Microsoft 365 E5 developer sandbox, provided you continue to use it actively for development purposes.

Where can I get help if my developer sandbox activation fails repeatedly?

Because the Developer Program uses a separate support infrastructure, you should directly contact Visual Studio Subscription Support or ask for guidance in the Microsoft 365 Developer Platform community forums rather than standard Microsoft 365 support.
