Hi!
Yesterday I wanted to start a new Office 365 trial service setup for my business and later I'd buy E1 licenses for users.
Unfortunately a few months earlier I've already started a trial period and after the trial period I decided not to buy licenses yet. And I've just forgot the admin account information of this earlier trial.
Now I tried to login into this earlier trial account and add licenses to it, but I simply can't remeber the admin account.
So I started a new trial with a new account and I started to configure it by linking domain nme to this new account. Bad luck, it says, my domain is already linked to an O365 service. I think this is the earlier forgotten trial account.
What should I do now? How to recover a forgotten admin account if no username is known, only the linked domain? How can I unlink my original domain from this forgotten trial account?
