Many posts related to PST having sizing issues but unable to locate an automated preventative on-screen message for the user. Our enterprise gets Help Desk calls from end users their PST is "broken", simply not working, or corrupted. Have been searching for an automated, on-screen messages when their PST needs attention, say at the 1, 1.25, and 1.50GB regardless of it's home location on the drive. Thinking a once-a-day scan would do the trick. That way we could address before it becomes a Service Technician's nightmare. Thank You.
