Managing personal Outlook.com account settings, security, and privacy
You're very welcome! I completely understand your concern, especially after trying the recovery form several times. Billing Support can check your subscription and billing details and let you know what options you may have. They may not be able to change the recovery process, but they can help point you in the right direction.
For the recovery requests, Microsoft doesn't provide the exact reason why a request may be flagged or why you haven't received the decision email. I’d recommend checking your spam or junk folder and making sure the information you enter matches your old account details as closely as possible.
