Service Update

Availability September 15th, 2025
Product(s) Email Security Cloud Gateway (CG), Mimecast Administration Console
Who's affected Email Security Cloud Gateway (CG), Administrators

Overview

Mimecast is moving to the next phase of the Mimecast Administration Console menu update. The new menu, designed to provide a more intuitive and scalable navigation experience, will be enabled by default for all users who have not already opted-out. This update follows a successful opt-in phase and incorporates feedback received from customers, including the reintroduction of menu search and favorites.

What's changing

We are updating the default Menu within the Mimecast Administration Console. This brings an updated navigation experience to all our Mimecast Administration Console users, making it easier to find and access the content you need.

All users who have not opted out will be opted in to the new Menu by default; any users who have already opted out will remain opted out, but we highly recommend all users switch to the new Menu, and provide us with feedback.

  • When will this happen?

This switch will happen on the 29th of September 2025.

  • Can I Opt-Out of the New Menu?

Users will be able to revert to the legacy menu via the new Menu switch in the top navigation bar; this option will only be available for a limited time. 

  • Updates we have made

Since the initial launch of the new Menu, we have added support for the Menu search and reintroduced favorites, along with other minor updates based on the feedback we have received. Thank you for your feedback.

  • How to provide feedback

To provide feedback, please follow the feedback process, and be sure to select New Menu as the product area.

Recommended actions

We highly recommend that customers continue using the New Menu, provide us with feedback, and follow Service Updates, to keep up to date with updates and timelines.

  • Stop switching your admin console around every year or so to make it look “new and fancy” … when we learn where something is, you help no one by changing it all around!  Its not helpful.
