Cloud Email Security - Office 365 integration setup

In this step-by-step guide, we will show you how to connect the CES with an Office 365 / Exchange online Setup.

For this guide we will assume you have the following:

1. Valid Microsoft 365 Business subscription
2. Working E-Mail setup
3. DNS server admin authority to change the MX record to CES Servers
4. DNS domain admin authority
5. CES Org. account with admin capability

1. Setup

2. Verification

Setup:

Configure the E-Mail gateway settings on CES “Email Services” (you will need to wait for the status to become “checked”).

The “Primary mail server” field needs to be the same as the Microsoft 365 domain DNS record.

Configure the Incoming Policy Set and Rules to identify who’s mailbox will be scanned by CES and what actions will be taken when scanning.

Change the MX record to CES on the DNS server
mxA.expurgate.net
mxB.expurgate.net

Verification:

Send a mail to the CES-protected email account, in this example:

Send a mail to usg5168@csosupport.cloud.zyxel.com

Login to the CES portal, go to “Reports” > “Email” and check if the mail delivery had been recorded by the CES.
