Hi,

I want to create an application that can subscribe to changes to outlook emails of my customers who have their own microsoft office 365 tenant/account. To do so I would have to create an application in my account that can make "create subscription" calls to subscribe to emails of my customers. I can create an application in my account but I can't find the clear steps for what my customers need to do to authorize my application(using application permissions) to make calls on their behalf. I see this document(https://learn.microsoft.com/en-us/entra/identity/enterprise-apps/grant-admin-consent?pivots=portal) but that already talks about giving admin consent to an existing application in my tenant.

Hi Sohil Gogri,

As per Microsoft documentation, managing user consent to apps in Microsoft 365, this setting controls whether users can give that consent to apps that use OpenID Connect and OAuth 2.0 for sign-in and requests to access data. An app can be created from within your own organization, or it can come from another Microsoft 365 organization or a third-party.

If you turn this setting on, those apps will ask users for permission to access your organization’s data, and users can choose whether to allow it.

Hope this helps.

This document talks about user consent. My question is how will my customers add my app to their entra ID? Once they've added it, this doc can be used to give admin consent to the app.

Hi Sohil, Does the customers belong to the same tenant or different tenant?
