What's New in 7.4

Branded Member and Join Pages

Group Welcome Email Templates

Portal Performance Improvements

Updated Data Room and Committee Templates

Single-Page Membership Management

Help / Support Request Form

Publisher and SPFx Improvements

SharePoint Online Content Security Policy Updates

Branded Member and Join Pages

EUM 7.4 adds CSS and JavaScript support for the Member and Join pages, giving organizations more flexibility to tailor external-facing pages better to reflect their brand, audience, and collaboration scenario. The result is portal entry points that feel consistent with the rest of your environment, whether you are onboarding clients, partners, vendors, or committee members.

Group Welcome Email Templates

The release introduces the ability to create and assign email templates for Group Welcome Emails. External users now receive clearer, more consistent onboarding messages when they are added to a group, and group owners get a reusable structure instead of having to build one-off emails for each scenario.

Portal Performance Improvements

Several portal-side updates are designed to reduce page load times and resource usage. For organizations running busy client, partner, or committee portals, this translates into a smoother day-to-day experience for the external users who rely on them.

Updated Data Room and Committee Templates

EUM 7.4 ships updated page templates for the Data Room and Committee scenarios, making customization and implementation faster. Boards, review groups, and external stakeholders get a structured and governed space to collaborate on sensitive documents, and your team spends less time configuring those spaces from scratch.

Single-Page Membership Management

Membership managers can now view and update the membership of every group they own or manage from a single page. As people join, leave, or change roles, the right people can keep access accurate without scattering requests across multiple screens or relying on IT for routine changes.

Help / Support Request Form

A new Help / Support Request Form lets end users submit a support request directly from the portal. External users get a clearer path to help, and administrators get a more structured way to receive and respond to requests rather than fielding them via email.

Publisher and SPFx Improvements

Behind the scenes, EUM 7.4 includes Publisher performance improvements, a bug fix to refresh the Publisher cache when core libraries are updated, and SPFx web part enhancements. These updates keep authoring and rendering performance steady as your portal content and component library grow.

SharePoint Online Content Security Policy Updates

The release also includes updates aligned with the Microsoft SharePoint Online Content Security Policy changes enabled in March 2026. This keeps EUM experiences reliable as the underlying Microsoft 365 platform continues to evolve.

Wrapping Up

EUM 7.4 focuses on the day-to-day work of managing external collaboration in Microsoft 365. The branded Member and Join pages, Group Welcome Email templates, and portal performance improvements enhance the experience for the external users you onboard. The single-page membership management view, Help/Support Request Form, and updated Data Room and Committee templates make life easier for membership managers and administrators behind the scenes. The Publisher, SPFx, and SharePoint Online Content Security Policy updates keep the platform aligned with the broader Microsoft 365 ecosystem.
