Exchange 2010 self Cert

If you only have a Self-Signed certificate, you'll want to modify your send and receive connectors so they are using just <servername> and not <servername.domain.local> as the response for EHLO HELO. If you have a cert that matched the domain name you have configured, configure your server so that cert is used for SMTP.

I have a digi cert but we deleted the self created cert.

Okay, so make sure your connectors have the website host name defined in the cert as their FQDN for HELO. You can do this by going to Organization Config\Hub Transport then right click on your Send connector and click Properties. The line there asking for an FQDN should match the FQDN defined on the cert. Do the same at Server Config\Hub Transport for your Receive Connectors.

send connector has mail.domain.com
 both receive connectors (client and default) have mail.domain.com

initially the client had the msg.domain which I changed to our exchange cert (mail.domain.com).

but I'm still getting the error message.

Here it is, looks ok.

Management role groups enable you to grant permissions to groups of administrators and specialist end users. These are p
eople who manage your organization or perform special tasks, like mailbox searches for compliance reasons.
If you want to manage permissions for end users, use management role assignment policies.

Tip of the day #84:

When you are creating a new Edge subscription, you need to run the New-EdgeSubscription cmdlet first on your Edge Transp
ort server, and then on an administrator console that is connected to your internal Exchange organization. However, beca
use Exchange 2010 uses remote Windows PowerShell, you can no longer use the Path parameter when importing an Edge subscr
iption file. Instead you need to use the Get-Content cmdlet to first retrieve and encode the data, and then pass it to t
he New-EdgeSubscription cmdlet, like so:

New-EdgeSubscription -FileData ([byte[]]$(Get-Content -Path "C:\EdgeServerSubscription.xml" -Encoding Byte -ReadCount 0)
) -Site "Default-First-Site"

Here is something else

The subject alternative name (SAN) of SSL certificate for https://msg.schulershook.net/Autodiscover/Autodiscover.xml does not appear to match the host address. Host address: msg.schulershook.net. Current SAN: DNS Name=mail.domain.com.

I also set this back to default.
