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:
- A bank employee sending credit card statements to customers
- An insurance company representative providing policy details to customers
- A mortgage broker requesting financial information from a customer for a loan application
- A health care provider sending health care information to patients
- An attorney sending confidential information to a customer or another attorney
- A consultant sending a contract to a customer
