Start course

Email Encryption Solutions in Microsoft 365 looks at how messages and attachments are protected both within the Microsoft 365 ecosystem and when they are sent to external recipients. This course outlines the various protection mechanisms at play, how they work, and how to use them. In addition to encryption and information rights management, we see how encrypted messages can be customized with an organization’s branding and what additional functionality comes with custom branding.

Learning Objectives

  • Gain an overview of Microsoft 365 email encryption
  • Learn how to implement email encryption
  • Understand advanced message encryption

Intended Audience

This course is intended for students working towards the SC-400: Microsoft Information Protection Administrator exam or those students wanting to learn about Microsoft 365 email message encryption.


There are no mandatory prerequisites required to take this course, but an understanding of how email works and previous experience with PowerShell would be beneficial.


You can customize the look of your organization’s encrypted messages as they appear in email clients and the encryption portal. Listed here are the elements you can customize. Apart from aesthetic options like background color, you can specify introductory, disclaimer text, and your organization’s privacy statement URL.

The look and feel of encrypted messages are determined by configuration templates. There is a default template called OME configuration that can be altered with the Set-OMEConfiguration PowerShell command. This command is in the Exchange Online module, and you need to have global administrator permissions to execute it. To create and remove new templates with new and remove OMEConfiguration, you need Advanced Message Encryption, which is available with an E5 subscription. 


The Set-OMEConfiguration command takes two parameters. The identity is the name of the configuration/template. If you’re customizing a new configuration created with New-OMEConfiguration, that becomes the identity value, configuration name. The next parameter is the element to modify, followed by the new value. To set the background color in the default configuration, the identity is OME configuration, followed by the parameter background color and the color value specified as RGB in HEX format. Next, we set the logo on a custom configuration called “Branding Config 1” with the image parameter and a PNG image file.
