A free program from Microsoft that provides developers with the tools, resources, and sandbox environments needed to build solutions for Microsoft 365.
Hi @Mike Sterlacci
Please be aware that Microsoft has updated eligibility requirements for new E5 developer subscriptions, and approval for a new sandbox is determined by the program’s current validation checks. Please refer to Microsoft 365 Developer Program FAQ | Microsoft Learn.
Please note that we're not Microsoft support, this is a user-to-user support forum. Moderators here don’t have backend access to Microsoft systems, so we can only provide technical guidance based on the public resources. Therefore, we’re unable to escalate cases, perform backend cleanup, or reset Developer Program profile or tenant mappings on behalf of users. Issues like this require manual intervention by the Microsoft 365 Developer Program backend team, which cannot be performed from this forum.
If you believe you satisfy the criteria and are still experiencing difficulties, the recommend next step is to contact Microsoft Developer Support for further assistance. Their support team is best positioned to provide direct help and resolve such issues effectively.
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.
Thank you for your understanding.
