SUMMARY
=======

In Key Management Server, a user's certificate has a valid lifetime of 18 months
by default. After that time, it will expire. Before this happens, the
certificate has to be renewed.

At approximately 12 months, the Exchange client or Outlook client will
automatically remind the user to renew their certificate. The user will receive
the following message when they log on to advanced security:

  Your security certificates are approaching expiration.
  Do you want to send a certificate update request to the
  Key Management Server?

No administrator intervention is required. If the user clicks Yes, the request is
sent to the Key Management Server. The new certificate is sent back in e-mail
and is valid for another 18 months.

MORE INFORMATION
================

If the user chooses not to update the certificate, then they will be prompted
again the next time they log on to advanced security. If they let the
certificate expire, they need to be re-enrolled to be able to use advanced
security.
