Secure Protocols: Encrypting Exchange
Enabling encryption in Exchange adds extra security by encrypting all the traffic between Outlook and Exchange. By default, all modern Windows computers that are part of a Windows 2003 Active Directory (which is the case with UT Dallas) use Kerberos to encrypt authentication between the server and your computer. However, once the authentication process is complete, the rest of the information travels across the network in plain text. By selecting encryption for all data, everything you do with Outlook will be encrypted, including calendaring, notes, journals, etc.
Enabling encryption requires one change in the configuration of Outlook. Click on Tools/Email Accounts. Select Microsoft Exchange and click on Change
In the Email Accounts screen, click on the More Settings& button
In the Microsoft Exchange Server window, click on the Security tab
After selecting the Security tab, check the box labeled Encrypt data between Microsoft Office Outlook and Microsoft Exchange Server
From now on, everything you do in Outlook will be encrypted, and no one would be able to read your emails or steal documents from you.
