Exchange 2013 - The connection to Microsoft Exchange is unavailable

Hi there,

i have some problems on my new Exchange 2013 Server: Here is the topology:

1 serveur 2012 in workgroup with the Hyper-V role

2 VM: DC2012 is the DC of the domain: intra.mydomain.com, Windows 2012

The other VM is member of the domaine, Windows 2012, Exchange 2013 SP 1 installed.

So, i have dc2012.intra.mydomain.com and mail1.intra.mydomain.com (another DC: DC2008, name: dc2008.intra.mydomain.com)

I have some troubles with the SSL and the connexion of Outlook outside the LAN.

In the LAN on a client, i launch Outlook 2010 and the autodiscver make the rest. The connexion is ok.

But i have a client not in the LAN, so i configured a SSL. I made a request. First Question:

In the ECP, Server, Certificate, i have 3 times "Microsoft Exchange Server Auth Certificate" and 3 times "Microsoft Exchange" with differents dates. Why?

I installed my PKI on the DC2012, and paste the request and download the certificate. I retuned on the exchange server in ECP, Server, Certificate and treat the pending request. In Services i checked IMAP, POP, IIS, SMTP.

Then, in Server, Server, Mail1, OutlookAnywhere, in url extternal: mail.mydomain.com and Authentification: NTLM.

In ECP, Servers, Virtual Directories i wrote the same url external and internal: mail.mydomain.com for ECP, OWA, ActiveSync, OAB.

In my DNS on the DC, i created a CNAME record for mydomain.com et i created a A record for mail. on a client if i make nslookup then mail.mydomain.com the IP is the LAN IP of my exchange server.

I modified the MX record of my public domain: mail.mydomain.com to point on my Public IP. That works.

On the client outside of the LAN, i installed the root certificate and the exchange certificate.

second question:

Why my client outside of the LAN can't connext with outlook.

Thanks a lot for your answers and sorry for the long post.

Alex
