Exchange 2013 .LOCAL and UCC Certificates

We currently have a small network with one old physical server with 2008R2 installed as a DC and on the same box is Exchange 2010. I know this is not ideal.

I intend to upgrade the network using two new servers and 2012R2, one to be set up as a DC and the other to be setup as an Exchange 2013 box then retire the old server.

Our current domain is .local and my concerns are that I will have problems with exchange, especially the UCC cert which will be setup for…

Mail.domain.com
autodiscover.domain.com
remote.domain.com

I’m concerned that without mailservername.internaldomain.local on the certificate I will have problems with outlook certificate errors which I have in outlook when I’ve set it up in labs, the only way ive gotten round these errors before is to put the FQDN of the exchange server on the certificate but can’t with a .local

All help appreciated

Thanks

You can create the zone domain.com on your internal DNS server
with host (a) records mai.domain.com and autodiscover.domain.com pointing to the internal IP of the exchange server or Canonical Names (CNames) pointing to the internal FQDN of  the exchange server.

You would of course need to create other hostnames on your external DNS that need to resolved by your internal clients to your external server in your new zone in the internal DNS.

Then you can configure the internalurl and externalurl for your OWA and ECP virtual directories to mail.domain.com using the commands

Get-ECPVirtualDirectory -Server ExchangeServer | Select Server, InternalURL, ExternalURL

 Set-ECPVirtualDirectory -Server ExchangeServer -InternalURL "https://mail.domain.com/ECP -ExternalURL "https://mail.domain.com/ECP

where ExchangeServer is the name of your exchange server.


Can refer to the following question: cannot log in to ECP/OWA using Administrator account in exchange 2013

You will need to set internalurl and externalurl for the other virtual directories as well
ecp
owa
ews
Microsoft-Server-ActiveSync
OAB
Powershell

And also set Outlook Anywhere to mail.domain.com using the command
Set-OutlookAnywhere -Identity  "ExchangeServer\rpc (Default Website)" -InternalHostname mail.domain.com -ExternalHostname mail.domain.com

Can also configure the virtual directories using the browser gui as described in
Configure External and Internal URL in Exchange 2013
