Sorting and Storing Exchange Email

At my company of about 80 computer users. Each email clients and suppliers back and forth in relation to projects that we are working on.

We were looking for a way to sort and store the email from exchange, into the folders on the shared drives that we use.

Currently we are just saving as then pointing to the folder on the share drive, however due to the volume of email that is going back and forth some employees are having a hard time keeping up.

Is there any software out there that can help with this?
