Using Outlook for Android for personal email and calendar management
Hello,
Just to be clear upfront since you are asking for account lockout assistance, this is a public community forum and everyone answering here is a fellow user, not a Microsoft employee. We have absolutely no access to the system or any customer accounts.
When it comes to account lockouts, Microsoft uses a fully automated recovery system. If you cannot get the standard recovery codes to work, that recovery form you have been filling out is genuinely the only possible way back into the account. Support agents are actually not allowed to manually reset passwords or bypass the automated system for security reasons.
Your best option right now is to keep trying that recovery form up to twice a day. Make sure you are doing it from a PC or phone that you used to check that email regularly and try to be on your usual home Wi-Fi network so the system recognizes the location. You can reach out to family or friends you have emailed in the past and ask them to read back exact email addresses and exact subject lines of messages you sent them so you can plug those into the form.
Keep trying as that form is literally your only way in.
