New Exchange server 2013 not allowing Outlook to connect

I have been in this business now for 15 years. I have admin'd multiple Exchange servers over the years but I have never set one up for production from scratch. This makes me a semi-noob. I have been fighting an issue for 2 weeks now and need help!

A new Exchange 2013 installation on a dedicated Microsoft Server 2012. I have purchased and attached a registered SSL cert for the mail server. Exchange itself is running fine. I have created multiple email boxes for users and email works perfectly. Each user can log in to OWA and the mail works as it should. They can all send and receive with no problems or delays. This holds true from inside OR outside the office.

I am not able to connect Outlook to any mailbox though.

When using Microsoft Remote Connectivity Analyzer, I get mixed results each time I run the various parts.

When I run Exchange Activesync Autodiscover, I get Connectivity Test Successful with Warnings.

When I run Exchange Activesync, I get Connectivity Test Successful with Warnings.

When I run Outlook Autodiscover, I get Connectivity Test Successful with Warnings.

When I run Outlook Connectivity, I get

"Certificate name validation failed.

      Additional Details

Host name mail1.domain.com doesn't match any name found on the server certificate CN=mail.domain.com, OU=PositiveSSL Multi-Domain, OU=Domain Control Validated.
Elapsed Time: 0 ms."

I have a multi domain cert and 3 domains listed so far: domain.com, mail.domain.com, and autodiscover.domain.com. I am not sure if this really is a cert issue, or if there is something I missed in the install.

If I ignore all of this, and try to configure Outlook, after putting in the information asked during setup, Outlook appears to take 3 steps:
1. Establish network connection
2. Searching for "mailbox" settings
3. Logging on to the mail server.

The first two steps work fine and I get the green checkmark. The third step fails however and throws the error "The action cannot be completed. The connection to Microsoft Exchange is unavailable. Outlook must be online to connected to complete this action."

I get the same error no matter in the office or out.

Can anyone help? My head hurts from pounding it against the desk!

Looks like you have an issue with the URLs (internal and external).

Run this script with the option "( -get)" to get all the internal and externals URLs that uses your environment
https://gallery.technet.microsoft.com/office/Script-to-configure-the-5a58558b

if you see that internal AND external address needs set up or have something like "mail.domain.local" that won't match your "mail.domain.com" so the certificate will bring errors.

Just reset using the same script with the option (-set -urlpath "https://mail.yourdomain.com") and it will update all the internal registry. Also, make sure that internally and externally the "mail.yourdomain.com" is accessible. Let me know if it worked for your or if you have anything else going on

OK,, few steps.

Open IIS Admin
Make sure that autodiscover.domain.com is bind to port 443 and certificate in IIS
Make sure that email.domain.com is bind to port 443 and certificate in IIS

Run Exchange Powershell

Get-ClientAccessServer | Set-ClientAccessServer –AutoDiscoverServiceInternalUri https://autodiscover.company.com/autodiscover/autodiscover.xml

Open in new window

Restart server or, IIS service and Transport service

Make sure there is A record for your autodiscover.domain.com in local and external DNS, for local DNS should point to internal emailserver IP.

I do not do much with Powershell so I didn't change anything before running the script. The results were almost promising I think.
For easy server info mail1.internal.local is internal server inside domain. mail.domain.com is external name...

Source: says I am running Exchange 2007 with a release date but it I know I am running Exchange 2013 so that is the first thing wrong.

Getting Client Access Information
AutodiscoverServiceInternalURi : https://mail1.internal.local/Autodiscover/Autodiscover.xml

Getting web services Info
InternalUrl : https://mail.domain.com/ews/exchange.asmx
ExternalUrl is the same which is correct

Geting Outlook Web Access OWA Info
InternalUrl : https://mail.domain.com/owa
ExternalUrl is the same

Getting Exchange Control Panel ECP Info
InternalUrl : https://owa.domain.com/ecp
ExternalUrl is the same. Not sure if it works because I usually connect using https://mail.domain.com/ecp and it works fine

Getting MAPI Info
InternalUrl : https://mail1.internal.local/mapi
ExternalUrl : (is blank)

Getting Powershell Virtual Directory
InternalUrl : https://main.domain.com/powershell
ExternalUrl is the same

This is the best money I have ever spent. I cannot not tell you how many times these folks have saved my bacon. I learn so much from the contributors.

Make sure you have external domain forward zone in your internal DNS and autodiscover.externaldomain.com too with your internl IP addresses. It's helping a lot with certificate binding.

Well the source of that is the web page on the technet
https://technet.microsoft.com/en-us/library/hh135098%28v=exchg.150%29.aspx?f=255&MSPPError=-2147217396

I really doubt it is wrong.

I'd do is to set all the internals and externals to the mail.domain.com

Create in the internal dns the zone "domain.com" if it doesn't exists and create 4 records:;
A to internal mail.domain.com,
CNAME to internal mail.domain.com
A to www => web page IP (type A)
A "empty dns record" to the same ip (domain.com).

And set up all the internals and externals url to mail.domain.com
script.ps1 -set -urlpath "https://mail.domain.com"

Make sure that your certificate counts with mail.domain.com and autodiscover.domain.com

So the default website bindings look like this

The Exchange backend bindings are

So you are saying I need to add the missing 443 bindings similar to what you are showing in your images?

The way I setup DNS was to add a new Forward lookup zone. I named it domain.com. In the records, I added 2 A records; 1 for autodiscover and the other for mail and pointed them both to the internal IP of the server.

You don't need to host names. This is how the ideal config should look like:
