I know this has been covered but I am really confused. We currently have an Exchange 2003 server that uses OWA. I have an SSL certificate with GoDaddy for mail.domain.com. We are in the process of upgrading to exchange 2010. Everything I read talks about creating a new certificate with:
Can I not simply use the existing Cert? Not that it's a lot of money, but we have a current cert with godaddy that won't expire for 2 years. Do I really need to purchase a new one because we're upgrading our server?
If I have to create a new cert that will mean there are 2 certificates with mail.domain.com out there. Is that allowed? Stupid question I am sure....but I really don't know.
