Here is the problem - outlook is getting the folllowing error messages for users on Exchange 2013
---------------------------
There is a problem with the proxy server's security certificate.
The name on the security certificate is invalid or does not match the name of the target site webmail.domain.internal.
Outlook is unable to connect to the proxy server. (Error Code 10)
---------------------------
all sites are configured to use Public domain name https://webmail.contoso.com/****
outlook anywhere internal and external URL set to the same
public SSL wilcard cert used
Outlook anywhere is functioning correctly on the internet - just internally you get the warning message - outlook connects okay.
if i browse to https://webmail.domain.internal i get cert warning, which i'd expect as the internal domain name is not listed in the public cert.
How do i resolve this? - i cant put the internal domain name in the public wildcard cert
