Registering your application in Azure AD

NOTE: We have built a quick registration tool for registering Skype for Busines Trusted Applications in Azure and Skype for Business Online, that eliminates the need to register an Application manually in Azure portal. You can find the portal at https://aka.ms/skypeappregistration

This article shows you how to register your service application in the Azure Portal at http://portal.azure.com. Before running your service application, you need to register it with Azure Active Directory, even if you are hosting your app outside of Azure. Application registration lets you set the permissions that your service applications needs and the sign on and application id URLs used for application authentication.

Register your application with Azure AD

Sign in to the Classic Azure Management Portal, then do the following:

  1. Click the Azure Active Directory tab in the left column and select the directory linked to your Skype for Business subscription.

If the permissions for Skype for Business do not show in the Azure Management Portal, one likely cause is that the Office 365 account is not associated with the Azure AD.
