Office 365 Message Encryption is an easy-to-use service that lets email users send encrypted messages to people inside or outside their organization. Designated recipients can easily view their encrypted messages and return encrypted replies. Regardless of the destination email service—whether it’s Outlook.com, Yahoo, Gmail, or another service—email users can send confidential business communications with an added level of protection against unauthorized access.
There are many scenarios in which email message encryption might be required, including the following:
- An employee sending credit card statements to customers
- An employee sending financial information to a member or Local
- An employee sending confidential membership information
- An attorney sending confidential information to a customer or another attorney
Recipients outside your organization who receive Office 365 encrypted messages can view them in one of two ways:
By signing in with a Microsoft account or a work or school account associated with Office 365. For details, see Send, view, and reply to encrypted messages.
By using a one-time passcode. To learn more, see Use a one-time passcode to view an encrypted message.
