I need to review our 3rd part certificate which secures our IIS / SMTP / ActiveSync services. Is there any sort of outage that is required after importing and enabling the new certificate? Does users PC's / Outlook need restart, mobile phones etc that use ActiveSync, or is it seamless?

No problem, simply get a new cert. and activate for services you want to secure and you're done. Clients will not notice it. lasse at humandata dot se, http://anewmessagehasarrived.blogspot.com

Hello, You can renew the certificate by referring to the following link: http://technet.microsoft.com/en-us/library/ee332322.aspx Thanks, Simon

That link is for Exchange 2010, I have Exchange 2007.

Digicert has a great tool for generating CSR's https://www.digicert.com/easy-csr/exchange2007.htm It free and you dont have to use Digicert. This will help you with the CSR. lasse at humandata dot se, http://anewmessagehasarrived.blogspot.com
