Message Routing - Monitoring Message Flow

This article contains information on using the Email Delivery, Email Security, and Message Center in Mimecast's Administration Console to troubleshoot email delivery, manage stripped attachments, and monitor email flow, including detailed descriptions of available functionalities and their purposes.

Administrators can use the Message Center, Email Delivery, and Email Security menus to monitor email flow, manage stripped attachments, or troubleshoot email delivery. Administrators can release stripped attachments, view all emails that Mimecast has rejected when performing security checks, and investigate why emails are in the delivery retry schedule (among others).

Most email administrators will be familiar with requests from end users about why certain emails have not been received or delivered. The viewers and queues in the Message Center allow Administrators to troubleshoot delayed or failed email delivery and view or release attachments stripped from emails.

To access the following functionalities:

1. Log in to the Mimecast Administration Console.
2. Select either of the following menus:

• • • Message Center
    • Email Delivery
    • Email Security
