I am using a personal PC. I have a personal microsoft account I used to buy an Office 365 subscription. I never created any azure or active directory ever. My computer is personal, there is no work or school account on it.
Recently I tried inputting my MS account details (user and password) into the portal for Azure and it logged me into the portal. In the Azure portal it said I was a user. I could not access any areas of the account however because I am not a "Global Administrator" and was denied all permissions. I read microsoft's documentation for Azure and it says that the person who creates the Azure account is the global administrator. So # 1, if I never created this account, who did and who is the administrator? And # 2, if simply logging in was the creation of it, then why doesn't Azure recognize me as the global administrator?
