Encrypt Emails in Outlook 2010 & Outlook 2013
For Windows users the process of encrypting a message is simple. You will be automatically enrolled for a certificate when you log onto your computer. This certificate is used to send messages with digital signatures. Its associated private key is used to decrypt encrypted messages that have been sent to you. The certificate and private key will follow you on the network and be available on any Windows computer that you use to logon. There is no need to manually import and export certificates when using different computers.
Note: The process for encrypting messages in Outlook 2010 is shown below, however the process is very similar for encrypting messages in Outlook 2013.
