Hi. I have a client with a 2007 exchange server. They are getting ready to move to my hosted exchange environment in the next few weeks.
They currently have a third party SSL certificate that expires in a few days. Because they are migrating about a week after that I was thinking of letting the cert expire but I wondered how it will affect the environment.
Will mail still function on active says devices and or exchange over https? It just seems like a significant amount of work and the cost of the cert if we are moving their mail.
