Windows 10: I can't login and can't retrieve my account back

Hi,I just created a new mail account for my business.I seem to have forgotten my password but can't retrieve it because the questions asked are for example:- to which email adresses have you sent out mails- what are subjects of mails you have sentBut it was braaaaand new. Haven't done **** with it yet, and so I can't correctly answer those questions. Tried leaving them blank but then I get a reply saying that I did not provide enough information for Microsoft to give me back my account.I created it with my business name in the email address so I really don't want to have to create a new one be
