Exchange server certificate expired, now OWA and Outlook RPC over HTTP don't work!

Posted on 2006-04-20

Over the weekend the SSL certificate expired on our Exchange 2003 server.  We are using are own server as the CA (which also happens to be the same server as the Exchange server).  OWA and Outlook's RPC over HTTP stopped working as a side-effect.

We've recreated an SSL certificate for "", and when you go to our webmail site from any old computer, you get a good certificate message.  However, if you're going to the webmail site from a computer that is on our domain and had previously been to the OWA site (and has a copy of the expired SSL certificate installed), you can't get past the SSL screen (page cannot be displayed error).

We then deleted any SSL certificates from our domain or "" on the test domain computer.  We found the correct certificate to install to get OWA working (there are 3 if you look at the properties of the CA server and it was the 2nd of the 3).  Any idea what we should do to get Outlook RPC over HTTP working?  Is there another certificate we have to install?

    Go and buy a certificate. That gets round all of these problems.
    Otherwise you are going to have to visit every machine, remove the certificate that you installed and then install the new one.

    Biggest reason why I tell everyone who does a deployment to use a purchased certificate instead of saving a few dollars by buying one.

    RapidSSL certificate costs $70/year. If you have any handhelds you have to import the root certificate, but that is a once only job.
