SUMMARY

This article describes the behavior of certificate revocation in Outlook Express.

MORE INFORMATION

Beginning with Outlook Express 5.01, certificate revocation checking is disabled by default. If revocation checking is enabled, users with slow connections may experience a long period of inactivity while a certificate's revocation status is checked. This behavior may cause the user to believe that Outlook Express is not working properly.

NOTE: This behavior only occurs if you install Internet Explorer 5.01 on a computer that does not already have Internet Explorer 5.0 installed. If you are currently running Internet Explorer 5.0, this behavior does not occur.

To enable certificate revocation checking, follow these steps:
  1. Open Outlook Express
  2. On the Tools menu, click Options.
  3. On the Security tab, click Advanced.
  4. Under Revocation Checking, click the revocation checking setting you want.
  5. Click OK, and then click OK.
