I need some advice on reducing the size of our mail stores by archiving PSTs (18+ month old emails) to somewhere else on the network where it's seemless to the end user (Outlook 2003/2007). I'd prefer to store them on the network and not the end users' machines because storage is cheap and it'll be safer.
The alternative option I was thinking of was looking for a tool that will archive attachments. People send 1 MB+ JPGs to multiple people every day. I think separating those out would be huge, ideally if we are able to replace the attachment with a link to the file. Or even simpler, deleting attachments for specific file types.
