Hello, Looking for small help we have exchange 2007 setup and just installing the exchange 2010 in the same org as part of the migration , firstly we installed the exchange 2010- CAS servers but after installing the same users started getting the certificate prompt (Security Alert) from the newly installed CAS server, we have changed and replaced the internal and external URL's into that new server but still the prompt is coming from new server ( Servername.domainname- CAS01.abc.com) so where we need to change to fix the issue until we can purchase the new certificate.
