I am a systems administrator, with little knowledge on Exchange- having said that, we have another building offsite at another state- we use an outside vendor to host our email- and use pop3 on outlook- our offsite (who is maintained by a IT service) had a exchange server on a sbs2003 and used pop3 connectors for their users-and our email host..... server was close to crashing and we decided to update to 2008sbs-and the IT service is going to migrate it this weekend- at the time of the purchase of the server I requested for them to add 20 more licenses to the exchange so we could put 20 of our users on it and take advantage of the features. (we have 100 users total counting offsite)- they told me to have the email host to point the MX record to the new server- because they were not going to use the pop3 connector anymore because sbs 2008 does not take it......and would have to use rpc/http for the users outside of their domain- at the last minute they tell me that it cannot be done because we would have to move all the remaining users to the exchange server- which would be 60 more licenses...... is there a way to take advantage for only 20 of our users of this outside server without this mess?


Thanks!

First of all SBS2008 does have a POP3 connector.  However as in SBS2003 this is designed for a transitional period.

Secondly SBS only supports a mximum of 75 users, therefore if you are going to be using more than this you need full Exchange 2007 and Windows 2008

I understand 75 users, i only needed 20 more than the 20 they already had, and leave the rest outside.
can we still use the pop3 connectors if my exstra 20 users are outside of the sbs domain?

you say you have 100 users total?

It's easier to have them all on your SBS server and as you say use RPC-HTTPS or OWA

Your option (if your POP3 users outside of your domain have the same domain name as the ones on your exchange server) is to setup a shared namespace as per: http://www.msexchange.org/articles_tutorials/exchange-server-2007/planning-architecture/exchange-2007-smtp-namespace-sharing-different-relay-domain-types.html

If you have licenses for 2003 then you can use them but what are you thinking of doing?

Standard Exchange does not have a POP3 connector, it's only available in SBS

you could setup the shared namespace but other than that you will need to bite the bullet and buy the extra licenses.
Sharing the name space is the correct way of doing it.  I think these instructions seem a bit easier to follow.  

http://technet.microsoft.com/en-us/library/bb676395.aspx

Basicaly there are 2 stages to do.  Firstly the domain needs to be setup on the server and exchange told that it isnt the only server for the domain.  Next up, the server need to know the address of the the other server, because it cant just look up the MX records as it points to itself.



An alternative slightly more messy way of doing it, is to setup the 60 users on a completely different domain, and then create a contact for each user within exchange to forward the mail from the main address to the different domain.  

The only problem with this is you may have trouble sending mail through through the temporary domains isp, using the main domain as the sending address.  But it may well work, just using authentication?

what about this:
change the mx record to point to the new server, add the twenty users- set up an new email server locally, possibly on a debian server running squirle mail- what would it take to do that?
it would be a lot cheaper than buyin 60 more licenses..... host my own pop3 mail for the people that wont be on the exchange server..... with a similar address but with one variance or something like that,
I would have to buy a new domain name, register it, and what else?
please advise....
thanks!!!
Do you mean so that the different users on the other email server would have a different domain for the email address?  You could do this, but its upto you if thats acceptable.  I would personaly attempt the shared namespace.

Also there is a free mailserver for windows which is pretty good, called hmailserver.  

If you go with your method, you'd need to consider how mail gets to the second mail server.  Ie do you have multiple public ip addresses to host a second server, or you will need to setup a relay domain in exchange, so that it accepts mail for the second domain and passes it internaly to the second server.

Again if you had another internal mail server you could still share the namespace, if you have a Windows server you could setup POP3 on this and use that.
