Regardless if you are already in Office 365, have plans to build out an extranet in SharePoint Online, or utilize any other Office 365 based services, then all users (internal and external) must exist within the underlying Azure Active Directory associated to the tenant. With Microsoft’s Azure Active Directory Business to Business (AD B2B), users can be setup as Guest Users within the tenant and do not require a full Office 365 license. Extranet User Manager is then able to onboard external users as Guest users in the underlying Azure AD through the Microsoft Graph API.
With EUM B2B, we leverage Azure AD B2B to provide the user authentication and EUM provides all the desirable end user functionalities for your external user management. This allows you to:
- Provide access to Office 365 and SharePoint Online as well as access to SharePoint On Premises, SaaS solutions, or Custom Apps
- Utilize guest user licensing from Microsoft
- Build a structured extranet in SharePoint Online and invite in hundreds and up to thousands of external users to collaborate
