SpamHero is a great solution for customers using Microsoft Office 365 that want better spam filtering.

Basic configuration

There are only two steps required for setting up SpamHero with Office 365:

If you sign up a domain for SpamHero that is already using Office 365, our provisioning system will attempt to do the first step for you, but it is a good idea to verify your settings.
  1. Login to your SpamHero control panel and go to the Settings > Mail delivery host page and enter the hostname from the MX record that Microsoft assigns to your domain. It will look something like this:
    example-com.mail.protection.outlook.com 
  2. Switch the MX records for your domain to the ones assigned to you by SpamHero (and remove all other MX records). The MX records can be found on the Settings > Mail delivery host page under the Required MX settings section of the page.




Important: To avoid interruptions in mail delivery, SpamHero should be added as a "Connector" in the Office 365 control panel.
