Frequently asked questions

Why is the On-Behalf-Of (OBO) flow important?
In Office add-ins, the task pane is a client-side app. The OBO flow allows your backend API to 'act on behalf of' the user to fetch data from Microsoft Graph securely.
Can we restrict SSO to only certain users in our company?
Yes, we implement User Assignment requirements and RBAC within Azure AD to ensure only authorized groups can access your application.
