With the usual configuration of Office 365 and Azure, there might be multiple Azure AD instances associated with your subscription. When creating registrations to whatever SharePoint-related apps that you might be using, if you create the registration to the wrong Azure AD, it can’t access the data in your SharePoint. Or at least without further configurations, it probably won’t get any data from your Office Graph API or whatever else you might want to use.
How to find the instance of Azure AD associated with your SharePoint Online
It’s simple, luckily! This guide will show you how to select the right AAD instance. It’s geared towards a case where you’re actually wanting to register a new app to your AAD, or if you’re planning to use an enterprise application. The last step (4.) handles that part.
So – don’t start by browsing to portal.azure.com. That’ll just let you access the Azure AD instace(s) associated with your Azure subscription – not your SharePoint Online tenant. Instead, follow these steps:
- Go to portal.office.com and choose Admin to access the administration portal. Note that you need to sign in as the global administrator.
- Then make sure you are signed-in in the right tenant! Each SharePoint tenant has an AzureAD and this is where we want to do the registration. Select “Azure AD” from the “Admin Centers” -section on the bottom left.
- If need be – choose the correct instance of AAD by selecting your account in the top right corner of the page. Since it’s a tenant-specific AAD instance, it should look something like this.
- The next step depends on if you’re editing Enterprise Application (4.1) or Azure AD instance -specific app registration (4.2.)
- Select Enterprise Applications > All Applications from the left.
- Select More Services > App Registrations.
