server is known as "exch-1.domain.local" internally but as "mail.domain.com" externally. Solution If you haven't already, you need to add your public zone ("domain.com" in this example) to your internal IP and setup a record to point "mail.domain.com" to the same IP as "exch-1.domain.local". I like using CNAMEs for this so you don't have to update 2 records should it

The exchange server has http://serverfault.com/questions/618309/exchange-2010-certificate-error-on-internal-outlook-2013-connections a wildcard SSL certificate installed *.domain.com, (for use with autodiscover.domain.com and mail.domain.com). The local fqdn of the Exchange server is exch.domain.local. With this configuration there is no problem. Now I started upgrading all Outlook 2003 to Outlook 2013, and I start to get consistently a certificate error in Outlook : The Name on the security certificate is invalid or does not match the name of the site I understand why I get that error: Outlook 2013 is connecting to exch.domain.local while the certificate is for *.domain.com. I was ready to buy a SAN (Subject Alternate Names) Certificate, that contains the three domains exch.domain.local, mail.domain.com, autodiscover.domain.com. But there is a hindrance: the certificate provider (in my case Godaddy) requires that the domain is validated as being our property. Now it is not possible for an internal domain that is not accessible from the internet. So this turns out not to be an option. Create self-signed SAN certificate with an Enterprise CA is an other option that is barely viable

When he tried to open it in IE9 (we're avoiding 10 & 11 for the time being because of legacy support issues), it gives a certificate error, i.e., "There is a problem with this website's security certificate". When I try to click on the link for "Continue to this website (not recommended", it won't load anything. I looked at the clock and thought A-HAH! It certificate error was off by an hour, since it hadn't updated to take account of DST, but even after changing that it still didn't work. I tried to open the URL in the latest version of Chrome, and that wouldn't work either. He has Firefox installed on the laptop as well, and this did load the site properly. Yes, I know the simple answer would be to use Firefox for this, but there are other 2013 certificate error users in our organization who are experiencing the same issue, and I don't want to have to deploy another browser merely to circumvent an issue which should be solvable. This isn't a server-side issues, since other clients can hit OWA without a problem. I've used SSL Checker to check out the certificate, and all's well (as I'd expected). It's a 2048-bit key, so there aren't any problems with the Windows update that forced usage of a 1024-bit key minimum. Options such as changing the publisher's and server certificate revocation, cleaning out the cache, and flushing DNS have proven fruitless, and I'm running out of ideas fast. Has anyone seen a similar issue and, if so, can you recommend a solution?

We have only a handful of users that are actually experiencing the problem out of the whole office. Just started yesterday. I was looking into as a DNS configuration issue but no luck. A hunch thinks it is MS patch that went wrong. For Outlook users they can hit "ok" a few times and things carry on again. Mostly annoy
