How to remove 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 removal 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_188.8.131.52&wfname=CS&supporttopic_L1=100101137&supporttopic_L2=100101139&seamId=100101113&modalityType=2&ccsid=635010674839491482
