How do I configure OWA in Exchange 2010

Dear experts,

We just install exchange 2010 in our organization and we can't figure out how to make OWA available over the web. I need to make webmail.ourdomain.com be accessible from the web.

For your time and help many thanks, M

You'd need to set the External URL for OWA Virtual Directory using the cmdlet

Set-OWAVirtualDirectory -ExternalURL :webmail.domain.com

Next, you'll need to purchase SAN Cert (this is for additional security/encryption) and have the SAN configured to include webmail.domain.com / autodiscover.domain.com / CAS NETBIOS / CAS FQDN

Next, your External DNS needs to have publish A record for webmail.domain.com to point to your external firewall, so all the internet traffic would point to your firewall and there by have firewall turn traffic towards your CAS box.

Simple isn't it :)

Do I need to buy the certificate can I just make it work with a local certificate?
You would need to buy a certificate.

You could surely, users would get the cert errors - you know where you get those errors where it would state - the website isn't authentic etc etc.

However, webmail would work easily w/o certs.
