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.
