How to go from UCC SSL Certificate for Autodiscover, OWA e.t.c. to simple self signed certificate on Server 2008 SBS
Posted on 2011-02-11
For reasons best not explained I have a few 2008 SBS Servers which were set up in an overly complicated way with regard to SSL. I was originally told that to get SBS running properly I had to create external sub domains for autodiscover.domain.com and owa.autodiscover.com e.t.c then get a multi domain (UCC) SSL certificate to cover all the various names and I've done all of this and everything has worked fine. I've since found out that I no longer need to go down this route and Server 2008 has been tweaked to make things a bit easier. I've been told that really I could make do with a simple self-signed certificate generated by the server and with just that autodiscover, OWA, Outlook Anywhere e.t.c. will still work just fine.
My question is, how can I "convert" a server that has an expired UCC certificate for autodiscover and owa e.t.c. to one that will function with a self-signed certificate, and how will it affect existing users laptops using Outlook Anywhere, iPhones e.t.c.?
