I want to use Exchange 2003 for Calendar only and NO EMAIL - HELP

This should be possible, but I'm at a complete loss.

I have MS Windows 2003 SBS with Exchange Server 2003

We are using the shared Calendar in Outlook which I want and I had setup interal email and external email for the users.  Here is my problem.

I can send an email to the external address  user@domain.com and they will get it within 1 minutes (outlook is set to check email every 1 minute).

The problem comes when someone send an email internally........it can take 40 minutes or longer for the email to come in, UNLESS you manually click on send and receive.

What I would like to do is just disable the email on Exchange Server all together and only use the shared calendar.

Another thing that might be important.  In the Outlook contacts I can have an internal contact setup as abc.  when you type in abc in the To field the email will be sent out over the internet and the person will get it quickly.  If you click on Reply after you receive that message, it goes to the users Exchange mailbox and hangs there forever.

Can someone tell me the errors in my ways!

Thanks for the help.

Someone needs to recognise that there is this demand for a shared calendar, cos they could mop up so much business.

But anyway...

Exchange is an email server. Don't try and fight that, as you will always lose. Once you connect Outlook to Exchange, Outlook will try and send everything through Exchange. Accept that and life is so much easier.
Configure the SBS machine as if it is responsible for all email, that includes going through the wizards.

Having to manually select send and receive usually means that something is blocking the traffic. What you will probably find is that by changing folders in Outlook the email will actually appear.

This is because the Outlook/Exchange communication is actually push. Exchange tells Outlook that something has changed (an email has been delivered) and then Outlook goes and looks at the Exchange server to see what it is. If that push packet is blocked, then Outlook just sits there. However when you select something that forces Outlook to poll the Exchange server, then the updated folder status comes in.

Number one cause? Firewalls.
Make sure that you have configured your firewalls correctly to allow outlook.exe total access. That applies to Windows firewall as well as any third parties.
Similarly, if you have installed or enabled any firewalls on the server, make sure those are configured correctly as well.

A couple of more questions if that is the case.

1.  My outgoing mail server settings in Outlook are all set for the smtp server at the ISP.  And I have external email disabled on the Exchange server.
     is it OK to leave it that way?

2.  All Mail delivery is going to PST files (or should be) and not to the Exchange Folders.
     Do you see any problems with that?

That being said, I cannot understand why if my outgoing mail server is at the ISP, that the email is even going through Exchange.  I'm sure I'm beating a dead horse here.

You were correct about the firewall.  I disabled the Windows firewall and tried it and it seems to be acting like I want it to.  Thanks!
If Outlook recognises that the the address is local, then it will attempt to send it via Exchange. Therefore you shouldn't try and stop that behaviour, instead work with it.

If you are having email delivered to PST files, then you can't be using shared calendaring. Shared calendaring requires the information to be stored on the server, so that it can be accessed by others when Outlook is not open. If you are using PST files at the moment, then Exchange is not actually doing anything.
