I have a problem. I'm the IT guy for a rapidly growing small business. A year and a half ago we had 4 people (including me) now we are up to 20 employees and a whole lot of emails going back and forth. We deal with customized promotional promotional so alot of the emails going back and forth have artwork and logo attachments for approval and revisions. As you can imagine the pst files grow VERY quickly. I have 2 perticular employees that fill up the 2 gig pst limit within a month. I know how to archive emails and split the pst files into archived files and trying to keep them under 2gigs (we all run office 2007). However here's my dilemma. I store all active (main) pst files on windows 2k3 server for easy backup, there's a daily/weekly/monthly backup schedule on the server. I keep archived pst files on users local machines to minimize network traffic. Local users machines do not get backed up and there are times when they really must be accessed. What I'd like to know is what other people use for a retention time. What would be a good standard to implement beyond which emails are no longer stored. And lastly what do i do with those employees that absolutely must keep their emails as far back as possible such as order processors that deal directly with suppliers and need to be able to pull up an email with attachment from 2 yrs ago at a whim.
