I recently bought a domain and with it an Office 365 email subscription from Godaddy. Whenever I try to add my email there, I receive the following message:
This seat's taken
Whoops! mydomain.com has already been used to set up a Microsoft 365 account at Microsoft®.
Before you can create any new users here, you must remove mydomain.com and any associated accounts from your previous Microsoft 365 account.
Sign in to your Microsoft 365 account on the Microsoft site.
Go to your Admin section.
Find the Users section, and edit or delete any users associated with mydomain.com.
Find the Domains section, and select mydomain.com to remove.
Come back here, and create your new Microsoft 365 accounts!
It might take some time after removing the domain before it's available here. Give it a few minutes before trying to create an account. Learn more
I honestly don't remember where that domain was setup before.
I contacted GoDaddy's support and their answer was that I should contact Microsoft
I can verify the current ownership of the domain. However, since it's new, I didn't create anything within Microsoft 365. It's possible this tenant is setup by someone else. Can someone help me remove the tenant so I can continue with the setup.
