Exchange 2003 you can find this easily, I need this for Exchange 2007. You're help is appreciated, thanks!

Hopefully you mean a commercial certificate, which will give you the maximum support. http://blog.sembee.co.uk/post/Exchange-2007-and-SSL-Certificates-Take-2.aspx Although I believe it is also documented on Technet. Simon.Simon Butler, Exchange MVP Blog | Exchange Resources | In the UK? Hire Me.

Yes, that looks good! THANK YOU SIR. (It's not a commercial certificate, it's from our own certificate server, it's still possible right?)

Personally I wouldn't use a self signed certificate of any description (so the Exchange generated or an internal CA) for OWA, unless you have control over 100% of the clients. I don't like the idea of telling a user to ignore SSL warnings. While you may tell them that it only applies to your site, users only tend to hear what they want to, and will just hear "ignore the warning". For a public facing site, use a commercial trusted certificate. US$80/year. Simon.Simon Butler, Exchange MVP Blog | Exchange Resources | In the UK? Hire Me.

Agree with sembee, UCC cert from third party provider i prefer go daddy, least expensive @ great support.MVP Exchange Server

Hi genson1980, Yes, it is better for you to use a commercial trusted certificate in a production environment. If you use self-signed certificate, you will have to ensure that clients, servers and devices that access any secured site trust your CA as a root.
