Have Exchange 2013 with wildcard cert. I'm getting the 'There is a problem with the proxy servers security certificate error' when trying to connect Outlook on the local network, if i connect from the outside world all is good.  The connection status tells me the url it's using and it is the external url 'webmail.mydomain.com' so i can understand why i'm getting the error but i just can't see how to get round it.

We found that you can not use a WildCard cert for Exchange. You need to get a UCC cert and make sure that you define all the subject alternative names correctly.

Hi, problem with that is the internal address is .local external .co.nz, as far as i know you can't have a non supported domain name on an commercially purchased ssl cert (anymore).

You probably haven't changed all of the URLs within Exchange to use your public name.
There some that you cannot change from ECP, it has to be done from the Shell. The most common one is Autodiscover.

Administration of Active Directory does not have to be hard.  Too often what should be a simple task is made more difficult than it needs to be.The solution?  Hyena from SystemTools Software.  With ease-of-use as well as powerful importing and bulk updating capabilities.

Something has to be wrong in Exchange or your DNS.
Have you checked the external host names are correct AND resolve to the Exchange server? It could be that something is resolving to an external web host.

Hi Simon.  I'll go through it again and see if i can spot the error. I actually didn't do the original install so could be something in there.  thanks Jamie
