I am just installing Exchange 2013 and I also have Exchange 2007 in my environment.  The problem is users on the 2013 Exchange server is getting "The name of the security certificate is invalid or does not match the name of the site" when they open outlook.

Please help

Have you installed a trusted SSL certificate on to your Exchange 2013 server?
If not then you probably have an Autodiscover war.

You have to change your FQDN to match the name on your certificates.

This is a common issue since 2010, it is consider a best practice to match your internal and external names therefore your certificate will be valid for both.

You only have to do that and of course have the name on your DNS server pointing to the IP.

I ran into this issue couple of days ago.

When you setup Exchange Server it creates a default self-signed certificate for internal use and the common name on it is usually the machinename.domainname, when you installed the new certificate you did with your external (internet facing) name which is normal but now you need to replacement he fully qualified domain name (FQDN) of the URL that is stored in the following objects:

The Service Connection Point for the Autodiscover
The InternalUrl of Exchange Web Service (EWS)
The InternalUrl of the OAB Web service


Here is what worked for me: http://support.microsoft.com/kb/940726 

It is for 2010 but may work for 2013.... Let me know!!!

The Exchange 2010 methods work for Exchange 2013 as well. The only addition is that you need to have a split DNS http://semb.ee/splitdns and will need to set Outlook Anywhere addresses through the GUI.

It seem that it's getting the old cert from Exchange 2007 instead of the Exchange 2013 Sever which I installed a Trusted Cert

This isn't uncommon.
Do you have a trusted SSL certificate on the old server?

This is probably the problem you are seeing:

Did you try my previous suggestion?

Did you change all your records to point to your new server?

If your outlook client still trying to open from the old server you still have something pointing to it you need to change.

Like I said I had the same problem, once I did the steps on the article it when away.

You need to post the full command that you are running and the error being returned.

Set-ClientAccessServer -Identity MYSERVERNAME -AutodiscoverServiceInternalUrl https://mail.DOMAINNAME.com/autodiscover/autodiscover.xml 

The mail.domainname.com is a SAN of the certificated purchase.

I think for this one you have to change "AutodiscoverServiceInternalUrl" for "AutodiscoverServiceInternalUri"

Ok.  I will try that now.
Now I also have users not getting emails on their phones anymore.  These users I moved from Exchange 2007 to Exchange 2013

Again, you have to finish the steps I gave you, then you have to change all your records to point to your new server.

The reason is, in your firewall and/or your DNS records are looking for their mailboxes on the old OWA box and it is not able to open them because they are not there..

Resolve the Certificate issue and make your 2013 box your "official" mail server by changing all your DNS records and firewalls port forwarding to the server and you should be ok.
