How to use one certificate on apache, iis and exchange?

Question

Apache HTTP Server

You need to buy a certificate for Microsoft exchanger 2013
They offer a UCC certificate.
Can we use it on other services?
If so, how can I get the key from the Exchange certificate request to install it in Apache?
Same question with respect to IIS
The servers are physically different.

Answer 1

Yes, you can use the same certificate on all services that you have specified.

Answer 2

When ordering a SAN/UCC certificate, don't forget to put in it the names that the EXCH needs, especially autodiscover :) How to get the key? I don’t know, it’s possible that there is no way, if Windows, when generating a request, does not allow you to mark the key as exportable. With the key, and the SAN/UCC having all the names to be used with, can be used anywhere.
