OST files get fragmented over time, so they can grow due to white space.<br />
The &quot;compact&quot; action is like a defrag, but is a short term gain - unless &nbsp;a large amount of mail has been moved elsewhere.

Any way to manage .ost files from a Group policy or Exchange standpoint?

Recently, with the deployment of Exchange 2010, my users will be receiving much larger mailboxes. However, with bigger mailboxes comes much bigger .ost files. I’m noticing the .ost files are growing to even larger size limits than the users mailbox size; thus, my concern is how to manage these .ost files to preserve users local disk space. <br />
Any advice? <br />
