I'd have to concur, especially if federating is in your Lync future. Besides that if you are utilizing smart phones/3rd party software it's *much * easier to use certs from an already trusted external CA. Otherwise you'll need to install Root CA chains on your devices for your internal CA.
We ended up using a hybrid of internal and external certs, but our internal PKI is mature, and we used 3rd party certs for all the Edge's. - Will On Wed, Jul 4, 2012 at 11:04 AM, Brian Desmond <[email protected]>wrote: > *Why does installing Lync necessitate a CA?
