Selecting an Encryption Type

The type of encryption you implement in your organization depends on the level of security your organization requires and whether you are using an international or North American version of Microsoft Outlook. Organizations that require strong encryption should use either DES or CAST 64.

As you evaluate what type of encryption is appropriate for your organization, keep in mind the following:

• The level of security for each of the different types of encryption
• International considerations for using Microsoft Exchange Server
• United States legal considerations for using Microsoft Exchange Server
• How your messages are moved from one encryption type to another
