With Exchange 2003 - you can use an IP address for the certificate name and use that IP Address to access Activesync - it works happily.  2010 is be a different story.

You will never prevent everyone from trying to access your server (who shouldn't), but with decent security settings and account lockouts etc configured on your server, together with minimising the risk (within reason), you should be fine.

Even if you just use VPN for remote Outlook Access, there is nothing to stop a client from pushing spam to your server via a virus on their computer!
Here is a walk through for exchange 2007:

With Exchange Server 2007 a new type of certificate is introduced; it’s called a subject alternative name (SAN) certificate. The interesting thing about a SAN certificate is that it allows us to include multiple FQDNs (aka common names) in one single certificate (Figure 1). This is very useful in regards to Exchange Server 2007, since multiple FQDNs are used by the Outlook 2007 client when accessing an Exchange 2007 server.

To answer the actual question.

You woukd have a single certificate and have both names.  It's a SAN/UCC or MultiDimain certificate, see the autodiscover section of my article here for the correct names:

I would personally use the same name for OWA and for ActiveSync, it makes no difference.

@ demazter I noticed I missed the boat entirely with the first post, and attempted to remedy with the second regarding the SAN cert that allows for multiple names.

I have posted a section of what I am linking to ever since I got in trouble from thermoduric where he stated:
The guidelines state that you should post a link to the original content with a brief description.

I am just trying to follow the rules here.

so i should just go with say "" certificate for both owa and active sync for the mobile access?

also is it still callled active sync in exchange 2007
Glen KnightCommented:
Yes it is ActiveSync in all versions of Exchange.

Just go with a single URL for both.  But don't forget the other names listed in my article.
