The two leading causes of Cyclic Redundancy Error (CRE) are PST file corruption and presence of bad sectors on the drive, where your PST files reside. This can be due to a malfunction in your Outlook app or times when you try to download email items off of Outlook. This is a huge indicator of the fact that there is something wrong with the hard disk drive or the PST file

Causes of CRC Error

There can be several causes of CRC error; some of the primary reasons are given below:

  • Power surges and abrupt termination of MS Outlook.
  • Malicious attacks can also make the PST files inaccessible and corrupt.
  • Presence of bad sectors on the drive where PST files are stored.
  • Loss of internet connection while sending/receiving emails in Outlook.
  • Accessing or sharing PST files on a network.
  • PST file corruption after Outlook upgrade.

How to Fix CRC Error?

  • Check for Hard Disk Errors
    1. Go the Start button and hit Run.
    2. Type cmd in the dialog box and press enter (Run as Administrator).
    3. Type chkdsk x:/f (Kindly replace the letter x in the command with the drive letter that you want to format) in the command prompt and press the enter button.
    4. This might take a while as the chkdsk process starts to repair your files.
    5. NB: if this process ends without an error then restart your PC before attempting to read your files off of the drive. Proceed to the next method if this doesn’t work for you.
