Users commonly maintain at least two PST files, and sometimes as many as five or more PST files. Managing them is an ongoing problem for users–for example, updating them daily, fixing corruptions, or reinstating lost PSTs. The problem is worsening.
Microsoft Exchange 2010 delivers a new archiving mailbox that can hold old email, including PST contents. I am sceptical of this solution. Exchange administrators won’t encourage users to upload PSTs back into Exchange, because this will threaten Exchange HA and DR.
PST files will continue to be used as personal, informally managed archives for some time.
