Hello i have renewed Exchange 2007 self singed certificate. now i wanna Deploying a Self-Signed Root Certificate with Group Policy. i came across this article please refer this article and will it work for owa 2007 http://www.unixwiz.net/techtips/deploy-webcert-gp.html please guide me

Group Policy will only work for domain-joined machines. I recommend using a 3rd party certificate instead. One that is automatically trusted by most clients - internal and external. Much cheaper in the long run.

I agree with Andy. Here is more information you may need.

I agre with Andy, buy a certificate. it will cost money but will save you a lot of support later. lasse at humandata dot se, http://anewmessagehasarrived.blogspot.com
