What is Mimecast and how do I use it?

Wilson School District #7 protects it's employee email accounts with an email security filter (Mimecast). Mimecast skims and redirects emails sent to your Wilson email address -depending on a number of variables.

Most of the time its junk emails that are redirected to a secure mail box, so you don't have to deal with them. Other times Mimecast will block emails that contain email security threats and sometimes Mimecast is wrong about what emails are junk. 
Typically, once a day you will receive an email from the WSD Postmater (postmaster@wsd7.org) and it will look something like this:

Mimecast Email

Once you receive this email, decide whether to Release, Permit or Block the sender/message.

Once you choose an option Mimecast will forward the email to your Office 365 inbox.

If you want to proactively check your Mimecast held messages, you can login to your Secure Email Portal - checkout this how to:
