Posted by on 10 June 2014 04:42 PM
The Outbound Filtering feature of McAfee SaaS Email Protection service will work with Microsoft Office 365. Included below are instructions to add a new outbound connector that will route all mail to the smart host. If you already have a connector that you'd like to use, simply edit it using the instructions below as guidelines.

The steps below assume that you have already configured your Outbound Servers page to allow mail from Office 365. If you have not, the setting can be found in the McAfee SaaS Control Console under Email Protection - Setup - Outbound Servers. Click the More Options button, and enable the Microsoft Office 365 checkbox. Click Save and allow 20 minutes for the changes to take effect.
