Searching Exchange 2003

[BKGarry]

Ok say you have blocked flash files and exe's from being run from the home drinves and sent over emails so your students intergate the flash files into Excell spreadsheets and play them there, then they start sending them over email.

 

I know what the files are called, but i want to do a search for every mailbox that has the files in there.

 

Any ideas on how to do this, if it is at all possible.

 

I am running exchange 2003 on windows server 2003 with Group Sheils Exchange (8 i think) and GFI mail Essentials
