Two tenants in our Azure account

Question

Hi all,

Prior to my start at my company, someone (no-one knows who) created two tenants on our Azure account. The one tenant is used to run our Azure services and that is working correctly.

The other one isn't really used and I'd like to delete it, because it's causing confusion. However I'm unable to do so, because no-one has Global Admin access to that tenant except of Microsoft Office 365 Portal. Is there a way to regain control over this tenant in our organisation? I don't know how to log on as Microsoft Office 365 Portal in order to assign the correct rights to me as Global Admin.

Hello @Francois ,

Thanks for reaching out.

I think this might have caused when a self-service user signs up for a cloud service that uses Azure AD, they are added to an unmanaged Azure AD directory based on their email domain. If you are an admin and want to take over an unmanaged tenant created by a self-service user signup, you can take over an unmanaged directory and perform tenant deletion .

I had answered to similar question in past, sharing it here for your reference. Hope this helps.
