Extract attachments from Exchange inbox

Sort of. There are several ways to do what it looks like you want to do:

Easy method: Create a new account with mailbox ("SUPPORT" in your case). Log in as SUPPORT, set up an Outlook profile, and open the SUPPORT mailbox in Outlook. Open the Properties for Inbox. Give the Global Group (or individual users) access to the Inbox (Read access is good). Now, anyone in the user group can open that mailbox over the network and read the mail there, including attachments. Give your own user account Read and Edit permission on the Inbox and Deleted Items folder so you can go in and clean out the old stuff from time to time without having to log in as SUPPORT.

Complicated Method: Set up a public folder on the Exchange server. Give the appropriate users or Groups Post or Read permissions. I can't talk you through this one because I don't have an Exchange server to play with in my current job.

The Public Folder is the route to go. Public folders get email addresses exactly like regular mailboxes do. So you can setup a Public folder called Support and it will have the email addy of support@mydomain.com.

Public Folders can only be created from the Client side, so you will have to use Outlook to do this. Permissions however are assigned from either but easier to manage in Exchange Admin.

Also if you want the address to show up in your GAL (Global Address List) you will haveto open up the properties of the Public folder from Exchange Admin. and go to the Advanced tab and uncheck the box Hide from address book.

Now to actually have the attachments removed from the mail and placed in a shared directory you will need to use a Rule, and since there is a rule wizard in Outlook I'll let it guide you through the steps. Just create the Support mailbox (not Public Folder), login and access it then run the Rules wizard.
