Outlook Plugin Authentication

About

This document describes logging into the Mimecast Outlook Plugin.

Authentication

Once the plugin is installed, you should see the "Mimecast" tab in Outlook. You'll also get a prompt that the plugin requires authentication. Clicking on that window or going to the Mimecast > Account Settings button will get you to the authentication page.

Once at the authentication page, select Authenticate under "Single Sign-On." You'll then log in using your O365 email address, password, and whatever 2-factor method you have set up.
