Q: Setup Wizard is asking me for Azure tenant. Where do I find it?
A: Azure tenant is the AD domain and is usually in the form of: mycompany.com or myliveid.onmicrosoft.com.
There are a number of ways to find your Azure tenant.
If you are using the new Azure portal, navigate to:
New Azure Portal -> More Services -> search for Active Directory -> click on Domains, and pick the primary domain
If you are using the legacy Azure portal, navigate to:
Legacy Azure portal -> Active Directory -> drill into the specific Active Directory for your Subscription -> click on Domains tab and look at for the domain name as outlined in the screenshots
