I get the following message when loging into Outlook Web Access using Internet Explorer 6.0 sp1. "Security Alert. The security certificate was issued by a company you have not chosen to trust. View the certificate to determine whether you want to trust the certifying authority." I then choose to view certificate, then I installed the certificate, but I still get the security alert on subsiquent login attempts. I am have Windows 2003 SMS with all patches for the OS and exchange. How to I get rid of the security alert?

The best way to get rid of the alert is to buy a certificate. Having a security alert appear when you are using OWA isn't very professional and you cannot have the certificate installed on every machine that could use OWA.

A starterSSL from RapidSSL will be fine.

I have another client with 2003 SMS with Exchange. They do not get the security alert message. We did noy buy any SSL software for that server. Any suggestions?

They can't be using SSL, or have installed the certificate on all the machines that you have tried to use.

Do you get an error if you connect to the other client with a new machine?

The bottom line is that certificates are based on trust. Within Internet Explorer there are settings on which certificates it will trust. If your certificate provider isn't in the trust list (which home grown certificates are not) then the security warning is generated.
This stops anyone from creating a certificate for a domain that they don't own and spoofing. Imagine the hassle from phishing if that was the case!
