Before integrating your Microsoft Office 365 managed domain name with Hosted Email Security, perform all steps recommended by Microsoft to complete configuration of Office 365 email management for your domain.

To configure inbound connectors, ensure that you have an Office 365 administrator account.

Some organizations use Microsoft Office 365 to remotely host their email architecture, allowing Microsoft to manage the day-to-day aspects of maintaining their email servers. Hosted Email Security integrates with Office 365 to provide additional security and benefits.

Configure Office 365 connectors to allow email traffic to and from Hosted Email Security MTAs.

Important:

Consult the Microsoft Office 365 help for information about adding connectors. Some Office 365 plans do not offer connectors.
