How to delete your Microsoft Office account

We accidentally arrived at this site, still being logged in from some hotmail account, which enabled us to log in here too. It’s all MS, after all. Alas, no account deletion options whatsoever. So the trick should be to know your original account (in our case hotmail), go there and delete it. If you have more info, feel free to complete. Otherwise try asking MS in person: https://support.microsoft.com/getsupport/hostpage.aspx?locale=EN-US&supportregion=EN-US&ln=EN-US&oaspworkflow=start_1.0.0.0&wfname=CS&supporttopic_L1=100101137&supporttopic_L2=100101139&seamId=100101113&modalityType=2&ccsid=635010674839491482
