We want to use Teams for our company.
But when I want to register, I get a message that an account already exists for our organization.
How can I find out the address with which this account was created?

I believe you need to contact Microsoft and figure this out / takeover / delete this!

It might been created as someone states a trial of some of the services within M365 with that domain mailaddress

Thanks for the answer. 
I had called Microsoft but for privacy reasons they are not allowed to give me any information about the account.

@adam deltinger 

Can you prove you own the domain?? Ex access to dns?
Yes, I am the owner of the domain. We have an exchange server in the company with the email addresses.
In this case you should be able too! I’d contact them again
In This case you should be able to then! I’d contact them again
