Mimecast Service for Outlook - Broken with Endpoint Protection

[simongatward]

Does anyone else use Mimecast with the  MSO Outlook add-in? Since switching over to Endpoint Protection, MSO is unable to connect to the Mimecast service. I have tried various exclusions and even created a policy and set Endpoint Protection to OFF, and we still get the connectivity problem. As soon as I remove the Malwarebytes Endpoint Protection agent from the PC, Mimecast is able to connect and works perfectly.

I have raised a support ticket with Malwarebytes, but just wondered if anyone else has seen this or a similar issue?

Hi @simongatward, we have a few other folks having this conflict. We are aware of the issue and we are treating it as a severity 1 outage. We are actively working on a fix, and will hopefully have something today. Mimecast is unable to connect while the Endpoint Agent service itself is running, it is not the protection pieces that are causing the problem.

The update is coming down this evening and through the weekend. Look out in your Endpoints \ (click an endpoint from the list) \ Overview \ Engine Version.

Updated build with the Mimecast fix is 1.1.0.199.

Engine version 1.1.0.199 looks like it has done the trick, Mimecast now happily communicating with the Windows service again. Thanks for the quick resolution.
