Hello,
I have Exchange 2013 and Outlook 2013 clients. I recently purchased and applied a godaddy cert for Exchange 2013 using the mail.domainname.com. After getting proxy and cert mismatch errors I found the solution to changing the virtual directories to the https://mail.domainname.com instead of it pointing to the .local name. The proxy error has now gone away but I am still getting the error below: The blacked out area is servername.domainname.local. I have done the Test email configuration on the client and do not see any reference of the domainname.local. The only place I see .local referenced is under the ECP Sub URL as seen in pic below. Please help?
