How to disable junk mailbox for all users in Exchange

There are 2 places where items get placed into Junk Mail folder, the server and the client.  You will be able to address the Server by adjusting the SMTP connector properties.  As for the Client (Outlook) you will need to instruct the users to disable the Junk Email filtering in the client software (which will vary slightly depending on the version of Outlook).

As for the server.  Open the Exchange Systems Manager.  Go to [Administrative Groups/First Administrative group (or whatever your group happens to be called)/Servers/(your exchange server in question)/Protocols/SMTP].  Right click on Default SMTP Virtual Server (or whater you have listed) and choose Properties.  On the General tab click the Advanced button.  You should see only one item listed (All Unassigned), click the Edit button.  Now uncheck all of the filters.  OK all of your windows and you have the Server side done.

As for Outlook I will comment on Outlook 2007 (i think it is the same in Outlook 2003).  Pull down menu Tools / Options.  On the Preferences tab click the Junk E-Mail button.  Select No Automatic Filtering.

I think this option is only available if you install the intelligent message filter protocol. I'm unable to edit anything under this only get to properites and nothing looks right. I don't think were going to mess with it though since it looks like it might be better to play with in 2010.
