Using older versions of Outlook for Mac in business environments
Hi Stacy! This is Raech. I'm an Independent Advisor and an Outlook.com user like you. I'm deeply sorry to hear about the issue.
I understand the difficulties of trying to recover an email account. Based on what you have described, it looks like you have already gone through the Account Recovery form online, which is currently the only form of recovery available and this is fully automated. Meaning, no support personnel from Microsoft is able to recover or reset the account for you.
Normally you can just resubmit the form twice a day at most until you are successful. However for newly created accounts that have no recent emails sent or more info to fill out in the recovery form, I'm afraid the account is not going to be recoverable.
Please do note that this is a public user-to-user community forum. None of us here work for Microsoft and it is beyond our capability to assist directly with account or login-related issues.
Sincerely,
Raech C.
