To become an Admin for my Microsoft Business 365, I have added into my business domain (under manage.whois.com) the TXT / MX records accordingly and waited for days. But it still returns "We didn't find the record you added for (my domain). Please check the values of the expected record's fields against the record you added, in case there is some typo. If you just added this record please allow 5 to 10 minutes for the change to be replicated through the system, sometimes it can take significantly longer depending on your registrar."
What I want is to buy a few Business 365 licenses and assign them to my colleagues (including my own account), but without Admin right it stops me buying the Business Licenses. How can I proceed further from here?
