Setting up POP3 on Exhcange 2010

I am in need of Setting up POP3/IMAP on an Exchange 2010 server for a group of consultants.  Right now they are using OWA but find it very inconvenient and they would like to use there native Outlook mail client.  So I can find instructions on setting this up on the Exchange box but then there is a piece missing that is the piece for connecting to the server.
The client needs to reach out via the internet to the exchange server.  I have a domain setup for Active Synch that points at my exchange server and my mobile clients have no issue connecting.  So how to I setup the below for POP3 or IMAP?
Server: ex2010.myhostedservice.com
Encryption: SSL encryption is required.
POP3 Port: 995
SMTP Server: ex2010.myhostedservice.com
SMTP Port: 587
SMTP Encryption: TLS* encryption is required.
SMTP Authentication: Yes, same as incoming server

Hi

If external then your ssl certificate must be valid. You can set the options for pop and imap either using the emc or ems. If you have a wildcard cert then you have to set it from powershell. Start the services for pop and imap and set them to automatic. If you have a load balancer in place you also need to ensure your ports for pop/imap are open.

Edward,

Thanks for the input.  I am still not sure how to get the user to see my exchange server.  So I can setup an A record to pop3.domainname and point it at my exchange server (which I have for my active sync clients and my OWA users) that works.  But if I use the same address for pop3 it does not work.  Are you saying the reason the email client is not connecting is simply because I do not have the certificate applied properly?

I am missing some essential piece of information here.  I can feel it but cannot figure out what it is.  I feel it has something to do with the way IIS is setup on the exchange server.

Is your dns records setup both internally and externally?

If you enter in your incoming server for example pop.domain.com then it should find your server provided it knows how to get there. You can also use the exchange test connectivity site to test connectivity to your server and see where it fails. If it is the certificate it will tell you.

Why not just use outlook anywhere for your clients to connect?

Event viewer will also gives errors if it has not applied the cert correctly by saying something like pop/imap cannot connect on TLS etc.

Big up Edward! POP3 is an awful protocol and external consultants sound like the kind of people who want mail on their laptops and their phones, then they download everything to their phone and complain they cant see their mail on their laptops!!!

Use Outlook AnyWhere as suggested, or at least IMAP (eurgh!)
