XADM: Renewing User Certificates in Key Management Server (192181)
The information in this article applies to:
- Microsoft Exchange Server 4.0
- Microsoft Exchange Server 5.0
- Microsoft Exchange Server 5.5
This article was previously published under Q192181 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.
