Missing Sandbox After Rejoining Developer Program

Question

I recently deleted my previous Microsoft 365 Developer Program profile and rejoined using a different phone number. My new profile shows that I’m in the program, but I don’t have access to a sandbox or the option to create one. Please help me provision a new Microsoft 365 E5 sandbox under my current account (<PII: removed>).

Dear @Leonardo Nunez,

Thank you so much for contacting Microsoft Q&A Forum. 

Please note that our forum is a public platform, and we will modify your question to hide your email in the description. We ask that you hide this type of personal or organizational information the next time you post errors or technical details, to protect personal data.

Based on your description, as a Microsoft Q&A moderator, my role is to guide discussions and connect users with helpful resources. While I don’t have the right to access to individual account or your environment in order to help you further, but I still try my best to support you using the resources available. Besides that, this may be a limitation with the Microsoft 365 Developer Program. After deleting and rejoining, the system may not immediately allow a new sandbox. Please contact Microsoft 365 Developer Program support using your new account and request a manual review/reset. Only Microsoft support can resolve this and enable the sandbox creation option for you. Here is the official support line for them: Developer Program | Microsoft 365 Dev Center 

You will see Microsoft Services Hub after clicking Support. However, if your account cannot sign-in it to use support, please check these articles:  

• Services Hub sign in FAQs | Microsoft Learn 
• Open Support requests | Microsoft Learn 

Once you can submit a service request, you can explain in it: 

• The old profile was deleted. 
• You rejoined with a new phone number. 
• The account is now active but cannot create a new sandbox. 
• Provide the current account email (e.g., your current account email). 

Small tip: include screenshots of the dashboard showing the missing sandbox option, if possible. 

Please note that this is a paid support ticket, which means it requires an active support plan or a one-time support purchase. However, the benefit of using this channel is that your inquiry will be routed directly to the Microsoft Product Group responsible for the specific service or feature in question. This team includes engineers and developers who work on the product itself, so they are best positioned to provide accurate, in-depth, and authoritative answers especially for complex or edge-case scenarios that go beyond publicly available documentation or community knowledge. 

Also, in case that you cannot use Service Hub service above, you can use this LINK to submit request with Microsoft (fees are applicable as well). 

I hope this information can help you in this case and appreciate your understanding. 

Wish you a pleasant day!
