Can I create any alert when my PST files is becoming huge?

HI FOLKS,
I’AM JUST WONDERING IF YOU HAVE ANY IDEA IF I CAN CREATE A BATCH, ALERT, VBS OR ANY SCRIPT PROGRAM THAT WILL ALERT ME THAT MY PST FILE ON MS OUTLOOK IS BECOMING HUGE. I KNOW THAT NORMAL PST SHOULD BE ONLY 2 GB SO WE CAN PREVENT FROM BEING CORRUPTED. I WILL BE GREATFUL FOR ANY OF YOUR SUGGESTIONS. THANKS IN ADVANCE..
