How to use Office 365 Message Encryption to protect emails sent externally

Email encryption provides additional layer of information security by making sure only intended recipients can read messages. If you are looking for a user-friendly email encryption solution for your Microsoft 365 organization, there is a native tool for that – Office 365 Message Encryption (OME). Now, although the OME name is still in use, the official, up-to-date name is Microsoft Purview Message Encryption. It’s not quite the same, since OME was deprecated on July 1, 2023. But, like with most name changes, OME is and probably will be used for a long, long time to come, so I’ll use it interchangeably. Anyway, from the user’s perspective, OME is the easiest encryption method to use: it can be configured so that it does not require any additional actions on their part. From the recipient’s perspective, this form of email encryption works seamlessly with Microsoft 365 accounts and offers an intuitive experience for all other email clients and email service providers. Read on to learn how to create a Microsoft 365 sensitivity label and use it in a transport rule to encrypt emails and files.
