Using Security Features in Outlook

Installation Modes and Feature Options for Secure E-mail Messaging

To get full security functionality in Microsoft Outlook 2000 under Windows NT 4.0 or Windows 2000, you must install Outlook 2000 with local administrative rights or with elevated privileges. (Full security functionality is automatically included with Windows 95/98.)

With full e-mail security, users can perform the following tasks:

• Read S/MIME V2 encrypted e-mail messages
• Send S/MIME V2 encrypted e-mail messages
• Read S/MIME V2 digitally signed e-mail messages
• Send S/MIME digitally signed e-mail messages
• Enroll in public S/MIME security
• Enroll in MS Exchange Advanced Security
• Read Exchange 4.0/5.0 secure e-mail messages
• Send Exchange 4.0/5.0 secure e-mail messages

Without administrative rights on Windows NT 4.0 or Windows 2000, e-mail security functionality is degraded to limited security or no security, depending on the circumstances.

With limited e-mail security, users can perform the following tasks:

• Read S/MIME V2 encrypted e-mail messages
• Send S/MIME V2 encrypted e-mail messages.
• Read S/MIME V2 digitally signed e-mail messages
• Send S/MIME digitally signed e-mail messages
• Enroll in public S/MIME security

With no e-mail security features, users can only read S/MIME V2 digitally signed e-mail messages; no other e-mail security features are available.
