Our system admin has been struggling with the issue of our network getting completely locked up when users open PST files from network drives. Apparently Microsoft is aware of this problem but there is no fix for it.
The entire local network is unable to use Outlook while this file is being opened (which may take hours). Is there a way to determine which user is opening the file instead of forcing everyone in the office to close outlook (like a traffic monitor or something)?

Microsoft says pst files should not be stored on network drives, so the long term fix is move them off the network drives.
In the sort term, you can configure a mirror port on your switch, and then run wireshark on a computer attached to that port for a packet analysis. The switch might also be able to show bandwidth usage per port on a web interface depending on the model.
Another option would be to use a program that shows open files on server hosting the network drive such as filemon.
