Azure AD App Registration for Office Add-ins
We set up Azure AD app registrations for Office add-ins, including manifest configuration, Graph API permissions, redirect URIs, admin consent, and the Entra ID settings that most teams get wrong the first time.
Azure AD App Registration for Office Add-ins Overview
Every Office add-in that uses Microsoft authentication needs an app registration in Microsoft Entra ID (formerly Azure Active Directory). The registration tells Azure who the add-in is, what permissions it needs, and which redirect URIs are valid. Get any of those details wrong and the auth flow breaks with error messages that point everywhere except the actual problem.
The parts that trip up most development teams: the app ID URI must follow a specific format for Office SSO to work. The WebApplicationInfo block in the add-in manifest must match the app registration exactly. Graph permissions must be split correctly between delegated and application types. Admin consent must be configured for any permission that accesses organisational data. And the redirect URIs must cover every domain the add-in runs on, including localhost for development.
We handle app registrations as a standalone service for teams that have the add-in code but cannot get the auth layer to work, and as part of larger add-in development projects. We document every setting we configure so your IT team understands what was created in their tenant and why.

Types of Azure AD App Registration for Office Add-ins We Build
Entra ID Registration Setup
We create and configure the app registration in Microsoft Entra ID: app ID, display name, supported account types, and the settings that differ between single-tenant and multi-tenant add-ins.
Office SSO Manifest Config
We configure the WebApplicationInfo block in your add-in manifest with the correct app ID URI and scope, the step most auth breakages trace back to when SSO is not working.
Graph API Permissions
We add the correct Microsoft Graph permissions to the registration, selecting delegated versus application permission type for each scope and flagging which require admin consent.
Redirect URI Configuration
We configure redirect URIs for every environment the add-in runs in, including localhost development, staging, and production, so auth callbacks work without URI mismatch errors.
Admin Consent Setup
We configure the admin consent endpoint so IT administrators can grant permissions in bulk during Admin Center deployment rather than each user being prompted individually.
Multi-Tenant Registration
For ISVs distributing to multiple enterprise tenants, we configure a multi-tenant app registration so the add-in works across customer tenants without per-tenant configuration.
