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 companyUSA.com and the other is company.com in Germany.
3) Both locations use @company.com for email hosted by a third party  Strato.com.
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 Strato.com.
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 user@company.com, user1@company.com going to your server and user2@company.com, user3@company.com 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.

@joelsplace --- please be aware that your comment about there being a database size limit of 75GB is incorrect.

From http://technet.microsoft.com/en-us/sbs/cc817589


What are the limits for the Exchange store?

Essentially, there are no limits to the Exchange Server 2007 Standard Edition database size. By default, Exchange 2007 SP1 sets a limit of 250 GB that can be changed if needed. Also note that you can have up to five storage groups with a maximum of one database per group, meaning that you can have up to five databases. In Windows SBS 2008, we use two storage groups (two databases) by default. Database performance is dependent on the number of processors, amount of RAM, speed of your I/O backplane, and storage array configuration. Proper mailbox management policies should be in place to prevent creating back-pressure situations that would affect the server's performance.

@B_Baren  --  You will need to make an additional modification in order for email destined to your Germany office to leave your server.  This is because if you try to send an email to GermanEmployee@yourdomain.com, your server will look in its address list and see that you don't have anyone at yourdomain.com by that name, and the message will fail.  The server will not send the message to the smarthost because it believes it is responsible for the entire domain.

The easy way to resolve this is to change your Exchange Server from authoritative to "Internal Relay".  There is a very good overview of this here:
http://telnet25.wordpress.com/2010/08/08/internal-relay-domain-forward-all-mail-with-unresolved-recipients-to-host/

(Even though that article is written for Exch 2010, Exch 2007 works the same way).

I must tell you, though, that using POP3 is never a good thing in the business world.  There are way too many things that can go wrong, and rarely a good solution to fix those problems.  If you are unable to work with your German counterpart to create a shared SMTP configuration, then you may want to consider using something like Office365 which will give you the full management and control over your email while easily allowing you to share domain space with the overseas office.

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.
