Which services do you have bound to the self signed cert? IIS? SMTP? do all your computers trust this self signed cert? or are you users gettting prompted with an error that the certificate is un trusted.

The best thing to do is change your self signed certificate for one that the computers trust.

also, how are you publishing your web services to the internet? with this same certificate?

Exchange should be published to the internet with a reverse proxy such as TMG or UAG

I only ever use a 3rd party SSL certificate and Microsoft recommend that you install one too, so if you are running with a self-issued certificate, you are in an unsupported configuration.

$180 for 3 years is all that it costs to install a 3rd party certificate - so it isn't wildly expensive and will save plenty of headaches.

If you are not facing any challanges and don't want yo spend money than renew certificate. but better to go for 3rd party certificate , which is easy to manage and won't face any certificate challanges which usually comes in self-signed certificates
