Setup a send or receive connector in your own email server for mail flow with Office 365

 

Applies to: Exchange Online, Exchange Online Protection

There are two broad parts involved with establishing mail flow between Office 365 and your organization's email server, also called an on-premises server. Each of the two parts has several steps. Part one is to set up email to flow from Office 365 to your email server. You might have landed in this article because you were working through setting up a connector for part one. Part two is to set up email to flow the other way, from your email server to Office 365. You can find an overview of the steps, followed by detailed procedures to complete all of them at Overview of the steps.
