Overcoming Challenges and Enhancing External User Adoption in Microsoft 365 and SharePoint

Microsoft 365 is a hidden gem-filled ocean. The external user collaboration is one of the heavily underutilized features. Without sacrificing security, M365 external users portal provides users with seamless integration capabilities. When it comes to using external user features to solve actual business problems, the possibilities are endless.

The majority of businesses adding external users to SharePoint or M365 tenant, limiting their access to file sharing and adding them to Teams channels and calls. I would compare this very basic use case for an external user to owning a Ferrari and restricting its speed to 10 miles per hour.

External user function can enhance your collaboration capabilities with vendors, sub-contractors, customers, temporary workers, frontline workers, students, community members and so on. Be it sharing files, managing projects, timesheets, tasks or information flow, the capabilities of external user feature extend beyond just file sharing.

I would like to highlight some of the underlying reasons pertaining to such a low adoption for external user feature.


1. External User Governance


Adding a new external user to M365 tenant:
There is a dependency on your tenant administrator when you add a new external user as a guest. This dependency may result in a considerable delay in the process, particularly if there are a lot of external users and frequent requests.

Tracking external user acceptance:
This invitation process is concluded upon acceptance by the guest user. Tracking can be quite challenging when there are a lot of external users, particularly when the tenant administrator needs to access Azure Active Directory to verify the acceptance status of the users. This onboarding is further delayed by the absence of auto reminders.
Lack of ownership by business users:
Not empowering business users with a workflow to manage adding external users to SharePoint and creates another roadblock for the mass adoption of this feature. Active Directory users and external users must have a mechanism for user management without creating any dependency on M365 tenant administrator. In many cases M365 users would like to adding external users for a limited period and giving them limited permissions. Lack of this level of management discourages an enterprise to fully leverage external users features.


2. Guest User Interface


Useability and UX is the key to successful adoption for any feature. Guest users may not know anything about M365 and for them, their portal or user interface is all that matters. Customizing users’ interface for guest users would cost a fortune. This is one of the reasons why companies are yet to see real benefits for the external user feature.

3. Identity Governance


Some of the challenges that I have highlighted above can be resolved by implementing Microsoft's Entra ID Governance. It allows you to manage identity lifecycle, build workflows, put an expiry to external users etc. However, there is a significant cost impact as customers must additionally subscribe to Entra ID P2 (formerly Azure Active Directory P2) plans or upgrade their M365 to E5.
