Cannot open your default e-mail folders. Microsoft Exchange is not available.

Hi guys
Before I pull my hair out, let’s see what the experts can help with.

I am a complete Exchange newbie. Previously worked with SBS where everything was easy and straight forward. The Company has now, rightly so, decided to upgrade MS Server 2012 with Exchange 2013, some VMs clusters and all things new to me.

I have built a test server to learn the new environment before the new equipment arrives and I have to install and implement it.

I have installed Server 2012 evaluation version with AD, DNS, DHCP and added 1 user other than the Administrator.
I have then installed Exchange server 2013 and setup – send connector, accepted domains, default address policy.

The created user is able to access mail via OWA and send emails to outside recipients and to the administrator but when I generate an account in Outlook I get the following error:
“Cannot open your default e-mail folders. Microsoft Exchange is not available. Ether there are network problems or the exchange Computer is down for maintenance”

I have spent countless hours trying different solutions found on the net, each time restoring the server from backup when the solution has not worked. Now I am asking for your assistance.

We have a lot of public holidays in South Africa at the moment so it might take me a few days to test and get back to you guys on success.

I suspect some DNS problems ? (Because OWA doesn't depend on DNS that much).
When you add the account to Outlook, and you press Check Username, does it work (i.e. the username changes to full name, and underneath will be the line)?

Yes, it populates with the server and users full names.

I have created a self signed certificate without changing anything from the defaults.
When opening OWA I get the following error:

I have viewed and installed the certificate on the laptop I am using for testing.
Another note that might change thinking - the laptop I am testing with is registered on a different domain.
Some more searching.
I have  I have assigned the certificate to the “Trusted Root Certification Authorities” area.
I can now open OWA without any Security Alert.
Still get the same response from Outlook though.

After putting my laptop on the new domain I was able to connect outlook to Exchange.
Now on to the next learning curve.
Awesome!
