MORE INFORMATION

To complete the certificate installation, you will need access to the certificate file. You can obtain the needed certificate file by using any one of the following methods:

• Copy the file to the local workstation by using removable storage media.
• Copy the file from a network share location.
• Download the file from the Web URL that is assigned in the Authority Information Access extension of the certificate or from the enrollment page for your CA certificate.

Install the certificate

To install the certificate, you must use the Keychain Access program. To start the Keychain Access program, double-click the certificate file. The Keychain Access program will automatically load, and it will display the Add Certificates dialog box.

• To install a trusted root CA certificate, follow these steps:
  1. Click the Keychain menu, click X509 Anchors, and then click OK.
  2. You will be prompted to authenticate through Keychain Access. Type your password, and then click OK.
     
     Note If X509 Anchors is not available in the Keychain menu, the certificate that you have opened is not a trusted root CA certificate. The most common file name extensions for this kind of certificate are .cer and .crt.
• To install an intermediate CA certificate, follow these steps:
  1. Click the Keychain menu, click Microsoft_Intermediate_Certificates, and then click OK.

Verify the certificate installation

To verify that the certificate is installed and that it is ready for use by Entourage 2004 for Mac, use the Microsoft Certificate Manager. To do this, follow these steps:

1. On the Go menu in Finder, click Applications.
2. Open the Office 2004 folder, and then open the Office folder.

   • Click the Apple Trusted Root Certificate Authorities option for an installed root CA certificate.
   • Click the Intermediate Certificate Authorities option for an installed intermediate CA certificate.

Verify that the newly installed certificate is in the appropriate certificate list. After you verify the location of the certificate, Entourage 2004 for Mac is ready to use the certificate for Secure Sockets Layer (SSL) communications.
