Is there a powershell script that can seach every database in my exchange 2007 cluster for a specific attachment in someones mailbox?  I am trying to track down who sent or receieved a specific attachment entitled "hot babes.jpg" . I have found a few scripts that will give me the size of attachments in each mailbox or even the type of attachments....but I can't find a script that will search for a specific file name.

any ideas? 

p.s. - yes I have tried exmerge and export-mailbox.  They try to move the items.  I don't want the users to know I am searching their mailboxes for that attachment name.
