Exchange 2007 on SBS 2008 - Where Do I Start

I am hoping one of you can give me a high level Step 1, 2, 3 outline of how to setup a simple Exchange organization on SBS 2008 with consideration of the constraints listed below.  I can work thought the details once I know the path.

1) Exchange 2007 is installed on my SBS 2008 server but not configured.
1) We have two locations running separate SBS 2008 domains.
2) My location is and the other is in Germany.
3) Both locations use for email hosted by a third party
4) The German location has Exchange properly configured with Strato as the smart host.
5) My users are setup with Outlook pop3 accounts pointed directly to
6)  It would be logical to work with my German counter part to configure my server, but the differences in language and time zones make it almost impossible.

All the articles and forums I have read have done nothing but make me more confused smart host, Edge Transport, Hub transport, MX records, TSL.
Where do I start?

I guess I'm confused about your current config.  Is Strato hosting your email or just your domain registration?  If Strato is hosting your email (that's what your post sounds like) then what is the German Exchange server doing?  Is it using it's POP3 connector to pull email from Strato?

Strato is hosting the email. Germany's server is setup with a POP3 connector and something for outgoing but I don't know what.  I have the user and password to setup the smart host connection, but no port number.  I have run the wizards to setup the POP3 connector and Smart host.
So you want, going to your server and, go to Germany.  Correct?
As far as the smart host goes the ones I've used have normal ports.  Try 25 and 587 to see if one works.
You have to setup an individual POP3 connector setting for each user under Windows SBS Console/Network/Connectivity/POP3 Connector/View POP3 Connector properties/Mail Accounts/Add to direct each pop3 account to the correct Exchange account.
You don't need to mess with edge transport, hub transport or MX records.
Think of it like a normal email setup where the POP3 Connector is your incoming mail and the Smart Host is your outgoing mail.  After you have Exchange setup and running you will want save everyone's pst files and then connect their Outlooks to Exchange and import their pst files.  Don't forget that SBS Exchange is limited to 75GB total storage.

You are correct. I will look at those ports.
Here are 2 articles with screencasts about setting up POP3 and Smtp send with a Smart Host.  They are both for SBS 2008.

Screencast: How to Configure Smart Host in SBS 2008 - Getting Started Tasks

For your situation it really is that simple.  All of the stuff about Edge Transport, Hub transport, MX records, is irrelevant to you.  Smart Host is for the outbound mail and TLS(SSL) is for security passing usernames and password for the POP3 inbound connection.

According to Email Server info for Strato, port 25 is fine for your Smtp send connection and the standard port(995) for TLS/SSL for your POP3 connection is also supported.

Thanks to both of you for pointing  me in the right direction.  I'll let you know how it goes.

Did that change in sp1?  I remember reading about the limitation when SBS 2008 came out.
The ultimate size didn't change.  Exchange 2007 before SP1 had a DB size limit set at 50GB by default.  This was done to avoid backpressure issues which are very common if you just increase the size of the database without making the other necessary adjustments.
