Intro

The guide will walk you through signing into the Mimecast personal portal. This can be used for managing your personal block list and viewing or releasing held email.

How To


  1. Go to the Mimcast site.
  2. Put in your External email address and click next. Mine would be MFey@calark.com. I will be using my admin account for the pictures so they will be a bit different.
  3. You will then need to sign into your Microsoft account/internal email, but this should already be signed in for everyone. Mine is feym@calark.com.
  4. You will need to put in your password and use MFA to authenticate. After that you will be signed in.
