A free program from Microsoft that provides developers with the tools, resources, and sandbox environments needed to build solutions for Microsoft 365.
Hello @Dror Levi
Since this is a user-to-user community forum, I can only provide guidance and troubleshooting suggestions based on my experience as a user and the information you have shared.
To begin, I recommend checking whether you meet the eligibility requirements for the Microsoft 365 Developer Program and an E5 developer subscription. You can review the eligibility and enrollment information here:Microsoft 365 Developer Program FAQ | Microsoft Learn
If you have confirmed that you are eligible but are still unable to complete the subscription process, please try again using an InPrivate/Incognito browser window. This can help rule out issues related to existing browser sessions, cookies, or cached sign-in information.
If your Microsoft 365 account or subscription was obtained through a third-party vendor or partner, I would also recommend checking with them to confirm whether there are any account, subscription, or tenant-related conditions that need to be addressed.
If the issue continues after these checks, you can contact Microsoft Support for further assistance. Please visit the Microsoft 365 Developer Program portal and select Support.
Then, follow the guidance in this article to submit a support request: Microsoft Engage Center Get Help
Once your ticket has been submitted, the support team will be able to review your case in more detail and provide further assistance.
I hope this information is helpful and that you are able to resolve the subscription issue soon.
