Outlook PST files are the warehouse of corporate emails containing the most critical organizational data. As nearly thousands of messages are sent and received through these files each day, they continue to grow in size. Unless the company imposes quotas to limit the PST file storage for each user, these files become highly overflowed or oversized. As a result, they start showing erratic behavior on reaching a definite size limit. In such instances, they are very likely to get corrupt and account to data loss. To effectively work around the issue, you should carry out PST recovery using advanced third-party software.
