Verify Routing

You can verify that Office 365 is routing email outbound via the avgcloud successfully by following the steps below:

1. Log into CloudCare Anti-Spam
2. Click on the Customer Name > Reports > Recent Messages > Outbound
   1. You should see messages from your organization's internal users to external recipients listed here
   2. If you do not see messages listed here shortly after they have been sent, this typically indicates a configuration problem with your Office 365 Send Connector
   3. Double check your configuration and use the Office 365 Message Trace tool found in the Mail Flow > Message Trace menu of the Exchange Admin Center to help you identify the issue

Inbound Configuration

The MX records for the domain will point to avgcloud. Office 365 should provide you with an inbound MX record, typically in the form "company-domain".mail.eo.outlook.com.

In your portal:

1. Click Enterprise Options > Enterprise Domains
2. Select Click here to add a new domain route
   • Alternatively, you can click the icon under the Edit Column to modify your existing entry
