A PST (Personal Storage Table) file is responsible for holding all the Outlook-related information. To repair the PST file, you should use an in-built Inbox Repair tool. However, if it is unable to resolve the problem then you should use a third-party Outlook Inbox Repair software to do the needful for you.

If you are using Microsoft Outlook as an email client and personal information manager, your data is stored in a PST file. PST (Personal Storage Table) is the main storage file of Microsoft Outlook, which contains all the folders, profile settings, rules, and Outlook configurations.

It leads to critical data loss and requires PST Recovery operation to be performed, if there is no updated backup available. When your PST file gets damaged, Microsoft Outlook inbuilt utilities can help you to work around corruption, without switching to backup copy of the file.

Basically, it is a function which is responsible for detecting any changes to data that are used across network or stored on storage devices. Microsoft Outlook PST employs CRC check each time when you open the file. If you get Cyclic Redundancy Check errors while trying to access PST, this indicates errors with your PST and in many cases with the hard disk. In other words, CRC errors while accessing PST are not indicative of Outlook problems but are actually of issues related to location where PST resides. When PST gets corrupted due to such CRC errors, you will require restoring it from the most recent backup. In case of any backup related concerns, you should alternatively use Outlook PST Recovery tools.
