We have a Visual Studio Team Services instance that is used by the company I work for. The company has an Azure instance. As far as I am aware there is no connection to VSTS.
When I was added to VSTS as a Visual Studio Pro level user some months ago we had to use my Microsoft Account as we couldn't use my work identity because my MSDN subscription is linked to my Microsoft Account as we could not link it to my work identity; apparently this was because we use Office365 in the office.
We now have problems adding Basic Users to VSTS. I enter the users Microsoft Account identity and I am told "No Identities Found".
I looked at VSTS Settings where I can see "This account is backed by the Default Directory Azure Active Directory." I can also see an "Azure Subscription ID". When I follow the Subscription ID link I end up at my Microsoft Account Azure instance. I had other users log in to VSTS and they too are seeing my Azure Subscription ID in VSTS Settings.
Why is this happening? How do Azure instances/accounts relate to VSTS instances/accounts Can I break the link between Azure and VSTS
