Microsoft is gearing up to release a new version of Office 365 and the new suite of tools will offer subscribers the ability to send encrypted emails. The feature that offers the encryption is called Office 365 Message Encryption. The tool supports a number of email systems including: Exchange Server, Outlook.com, Gmail, Yahoo, Lotus Notes, GroupWise, and Squirrel Mail. Users can send an encrypted message and the receiver will get an email with an attachment explaining that the message is encrypted. They can double click the attachment to open another browser window and authenticate before accessing the message.
