I have a client with a SBS 2011 server who changed the email domain from mail.XXX-uk.com to remote.XXX.com. The internet domain name wizard was run reflecting the new domain and hence the new remote domain name of remote.XXX.com and a new verified SSL certificate was installed. Outlook Web Access and Remote Web Workplace work fine. All the internal clients appear to be connecting fine but the 2 remote clients which are Outlook 2016 are not connecting when using Outlook Anywhere and they get an error message "there is a problem with the proxy server's security certificate. The name on the certificate is invalid or does not match the name of the target site mail.XXX-uk.com." The actual target should be remote.XXX,com.
I did have a problem with the mail.XXX being stuck on the Exchange 2010 smtp service but it appears to be cleared now.
