This will open the message properties along with the message headers. To get the message headers from an email, first open the email in Outlook, then click the down arrow in the Tags section. This is a Message Header Analyzer, which saves quite a bit of time digging through the text of a message header. I discovered what was happening by use of Microsoft Remote Connectivity Analyzer page,, specifically, the Message Header Analyzer tool: However, the SMTP relay server still was functioning. I had a client where I was decommissioning their last server on-premises and setting up email to be sent directly to Office 365 from their multifunction devices.Īfter already checking the Authentication SMTP checkbox, sending mail directly from the scanner did not function. To enable or disable SMTP AUTH, there is a new checkbox available for Active Users with a mailbox in Office 365-”Authenticated SMTP.” This is found by clicking the user in Active Users, Mail, then Manage email apps.Īuthenticated SMTP needs to be checked to send mail out either through a relay server or direct through a copier/UPS/etc.-essentially wherever modern authentication is not possible. The only accounts that would need it are accounts that are connected to by a relay server or newer multifunction devices using a address, for example. As a security recommendation, SMTP AUTH for Office 365 should be turned off for all accounts that don’t need it. As such, Microsoft introduced the ability for SMTP AUTH client submissions. Multifunction devices, UPS units, etc., however, have not updated yet to support Modern Authentication. Modern authentication has been introduced, which is supported by Microsoft products. Office 365 has become more and more secure as an ongoing theme. More info can be found on the Office 365 blog. Any on-premise devices or applications would then send their usually unauthenticated emails through this relay server and its outbound delivery settings to Office 365 would connect to through port 587 using TLS.Ī positive trend, however, in the last many years is that the devices have been capable of TLS/StartTLS, and therefore are able to send mail directly to Office 365 at.

When migrating email to the cloud, the main requirement usually still needed is a server running the IIS6 management tools with SMTP relay configured. Perhaps the need is a physical fax card in a server or local storage for video capturing. There is usually a need for an on-premise server for something. Traditionally, even when moving to the cloud, it’s rare to move everything to the cloud.
