Mimecast Online Inbox/Held Items

Mimecast is an Email security service that provides advanced protection against threats. All emails pass through this securty service before reaching you outlook inbox. To view any emails that have yet to arrive to your outlook inbox Follow the instructions below

Go to the Mimecast tab

Select the following menu item:

Online Inbox

A page opens listing the items sent or received over the last 30 days.

Note: By default, the last 25 messages are displayed in reverse date order, with the most recently received email displayed first. To access more messages, scroll to the bottom of the list and more items will be retrieved.

To preview the email, simply click on it. From the message preview you can Reply, Reply All and Forward the email.

There will be times where mimecast will withold an email if it deems the email suspicious. Messages can be released or rejected either individually or in bulk. You can also block addresses or domains when messages are released or rejected. Images are not automatically displayed for held messages. You can choose to download the images for each message, after considering the security risk of doing so.

We have policies in place that place messages on hold. These could be based on spam, attachment, or content examination policies, designed to prevent unwanted emails from reaching your Inbox. The Personal On Hold viewer allows you to view the emails that have been held, and decide if you want to release them or reject them.

If you do not release or reject a message from the Hold queue within 14 days, it is automatically removed. You will still be able to retrieve the email from the archive, if this is configured by your Administrator.
