I have an Exchange 2013 server running on Windows Server 2012 R2. I am trying to figure out what steps I need to take in order to install a wildcard SSL certificate that already exists. This wildcard certificate is currently being used off-site for our websites, and I would also like to use it for our Exchange server which is on-site. Everything I have read so far assumes one does not have a pre-existing certificate and is therefore not much help to me. Can anyone assist me in this? Thanks!
