I am getting the error "The action cannot be completed. The connection to Microsoft Exchange is unavailable. Outlook must be online or connect to complete this action" OWA works fine without any certificate errors. I tried the website www.testexchangeconnectivity.com
all all the tasks pass except for the last one with the following error.
ExRCA is attempting to build certificate chains for certificate
A certificate chain couldn't be constructed for the certificate.
The certificate chain couldn't be built. You may be missing required intermediate certificates.
I am using SBS 2003 as a single server.
