There is no reason to compact the OST. You should just create a new OST. &nbsp;<br />
<br />
Since the OST is just a mirror of your online mailbox (based on how far back you have it set for). &nbsp;Recreating is the best, cleanest and most reliable method. <br />
<br />
<br />
&nbsp;To do this:<br />
Close Outlook and delete or rename the OST. The next time you open Outlook it will &nbsp;recreate a new clean OST.
