Office 365 - Getting Started with Message Encryption

With Office 365 Message Encryption (OME), you can send and receive encrypted email messages between people inside and outside our organization. Office 365 Message Encryption works with Office 365, Yahoo!, Gmail, and other email services. Email message encryption helps ensure that only intended recipients can view message content.

Why would I want to use OME

Have you ever had your email or documents shared or given to other people than you intended, or seen your company’s information shared with people outside the company by accident? Maybe you have information that you want to share confidentially with only a few trusted colleagues for purposes of collecting feedback, but you’re concerned that the information may get leaked inadvertently before you are ready?
