Autodiscover Exchange 2013 -- Turn off Connect to proxy servers that have this principal name in their certificate

Hi,

I am having issues with Exchange Server 2013. Autodiscover is checking the box (Only Connect To Proxy Servers That Have This Principal Name In Their Certificate). How can i disable this.

I have tried:
Set-OutlookProvider EXPR -CertPrincipalName none

but did not work.

You need to reconfigure Exchange to use your public name everywhere. That includes changing the internal and external host name for OWA, ActiveSync, Outlook Anywhere etc. Use a split DNS system to ensure the name resolution goes the correct place.

There should be no reason to change the OutlookProvider value if you configure the host name in Outlook Anywhere correctly.

Internal server names are not allowed on SSL certificates that expire past November 2014, so the switch to split DNS using the external name needs to happen at some point, you may as well do so for a new implementation.

What is the objective with wanting to disable the function?
If your SSL certificate is for host.example.com then fine. If it is for *.example.com then you can have problems, but usually only with Windows XP clients.

Outline the original issue, not what you believe is the fix.

Hi Simon.

Our certificate is for exchange.domain.com

But our proxy address is mail.domain.local

And it's looking for proxy address in certificate

Your certificate must have exchange.domain.com listed as a subject alternative name (SAN) entry or be the principle name (the default name) if the default is something else but contains the san entry you can Set-OutlookProvider EXPR -CertPrincipalName exchange.domain.com
