This article describes how to enable on-premises line-of-business (LOB) applications and devices to send mail to Microsoft Office 365 mailboxes. You may want to do this in situations in which you migrated all your mailboxes to Office 365 but where you don't have an on-premises mail server such as Microsoft Exchange Server. For example, you may want to send mail from on-premises printers or scanners to Office 365 users.

Note This article describes how to enable on-premises LOB applications and devices to send mail to Office 365 mailboxes only in a domain for which you are authoritative. This article doesn't discuss how to enable applications to use Office 365 transport servers to relay to other domains that you own. The mail relay scenario is beyond the scope of this article. For more information about how to set up a mail relay in Office 365, see the following Microsoft Knowledge Base article:

"That was then, this is now."

5th and K is a Microsoft Office 365 Partner. We date back to punch cards. 
We are IT people who in 2009 knew that Microsoft was pulling the plug on selling disks in a box, computers to live on premise, and the need to buy vs rent "Subscription based" We purchased the domain and populated it with "all things Microsoft Office 365" which not to long ago was known as BPOS. 
As a Microsoft Office 365 Partner/Advisor we get paid by Microsoft to help you, to assist you to give you knowledge on why you are not refreshing your server, buying one more spam client, or one more VPN client... gone, gone, gone! 
Our staff has deployed on premise in hundreds of companies. 
"That was then, this is now."
