I have a problem when setting up a MS Outlook 2013 client. I'm trying to connect to the MS Exchange ActiveSync email server. I have installed the certificates for the mail.ourdomain.com, but there's also a problem with autodiscover.ourdomain.com, which doesn't have a certificate. I can add the account, it says "Congratulations! You have successfully added the account" or something like that, then it asks me to restart Outlook, which I do, and then it displays and error, that it cannot connect to the proxy error, because of the certificate problem. Any suggestions ?

You should be using a SAN certificate and adding the appropriate domains to it, such as mail.domain.com, autodiscover.domain.com, etc.
