We have been testing Offic. I have my email working with my address as myname@mycompany.onmicrosoft.com. We are now migrating email to Office365. I have added my domain to office365 and configured my MX record as specified.
Do I have one just one mailbox or two, i.e. myname@mycompany.onmicrosoft.com and myname@mycompany.com? If I have just one, which address is it?
