A year ago I installed an Exchange 2007 server. I also installed a third party UCC certificate at the time and it's been working great. So now the certificate is close to expiring and I can't find too much info on renewing the certificate. When I've renewed a certificate for IIS, it's an actual renewal request but from what I've read for Exchange it's more complicated. It's there a "renewal" process for Exchange, or do I have to follow the process I orginally used and simply replace it?
