BlackBerry messages not getting delivered.

Hi, I've just setup the BlackBerry Enterprise Server for the company. I've never done this before and was going purely on documentation. Running into some problems...

BlackBerry Enterprise Server 3.6.2 (UPDATE)
Exchange System Manager on BlackBerry Server (UPDATE)
Windows 2000 Advanced Server (UPDATE)
Windows 2000 Advanced Server (NS2)
Exchange 2000 on Exchange server (NS2)

The paranthesis indicate server name. UPDATE is the BB server and NS2 is the Exchange Server

I've setup my user account on the BlackBerry Enterprise Server (I used the desktop manager to connect my handheld to my desktop outlook as well). When I try to send emails from my BlackBerry handheld, I immediately get a message on my desktop outlook saying:

"This message is used to carry data between the BlackBerry Handheld and an associated server. Please do not delete, move or respond to this message - it will be processed by the server."

This message sits in my desktop outlook mailbox and nothing ever comes of it, if I go back to my handheld it eventually says "Message Undeliverable" or equivalent.

My user account on the BES knows my PIN and all that and it says my Exchange Server name.

The only thing I'm not sure of is the CDO.dll - There is no actual CDO.dll file you can just download, you have to install the patch. I installed the patch on my Exchange Server. I tried to install the patch on my BlackBerry server but it errors out. So what I did was copy the cdo.dll I found on my exchange server (NS2) to my BB server (UPDATE) and ran the regsvr32 cdo.dll on UPDATE (don't even know if I had to do that) . I never ran regsvr32 cdo.dll on the Exchange Server. I think when I try to install the patch it needs Microsoft Exchange - which the BB server doesn't have.

Well I just realized something, in the documentation it points you to download the patch by what version Microsoft Exchange you're running and what version  Microsoft Outlook your clients are running. For Exchange 2000 it has a file for the clients running Outlook 2000 or earlier, and it has a file for the clients running Outlook 2003. It does not say anything about Outlook XP/2002.  Currently I am running the Outlook 2000 or earlier hotfix. This is the file I'm currently using...

Our users are on Outlook XP/2002 or Outlook 2000

My questions:

Does the CDO.dll patch only need to be applied to the Exchange Server?
Do I need to apply "regsvr32 cdo.dll" to the Exchange Server only? And if so does that stop services, should I do that after work hours?
Will I need the cdo.dll / patch / hotfix for Outlook 2003 instead of the Outlook 2000?

The following CDO hotfixes can be obtained from Microsoft support. These hotfixes are the most current versions and have been tested by BlackBerry Technical Support. It is their recommendation to obtain the appropriate fix for your environment and apply it to your BlackBerry Enterprise Server.

Thanks guys but I've solved it. I made sure the users were added on the BB server, and then I used the Desktop Connector to sync the BB with my Exchange mailbox. I thought this was all, but I missed one thing. I logged into and added my exchange mailbox account. Then it wanted me to install the "mail connector" on my computer. I installed it then rebooted my computer, and the mail connector was active. I went on the BB's wireless and could now send and receive emails using the BB and the BB was using my Exchange mail account.
