CRC Error Copying an Outlook PST File

Microsoft Outlook with a corrupted PST cannot perform general mail operations.

The reasons for corruption can be unexpected shutdown, network file sharing, virus infection and similar others. To repair such corrupted files, Outlook provides you a built-in tool called Scanpst.exe. However, if this fails, you can recreate the PST file provided a full backup is present. If not, you should repair the damaged file using third-party PST Repair applications.To illustrate, take a practical example when you try to copy your Outlook PST file from its root folder to a different location on the hard disk or another media.
