The Cyclic Redundancy Check (CRC) errors are caused when there is a problem in the file media or when a file is not properly transferred to another storage media. These CRC errors can also appear in the PST files that are used to store the information of MS Outlook. A PST file can get corrupted by other reasons as well such as virus infections, power surges, abrupt system shutdown, etc. In such cases, you should use appropriate corrective measures to rectify the problem. However, if you are unable to resolve the issue then you should use a third-party PST recovery software to repair the corrupted PST file.

Consider a scenario wherein your workstation is shifted to another location in your office. You create a backup of all your important data including the PST file of Outlook 2003. However, when you import the PST file in the new system you are not able to download the emails. In this case, few error messages may be displayed, they are:

· File path\filename.pst could not be accessed. Data error. Cyclic redundancy check.

Where, path is the location of the PST file and filename.pst is the name of the PST file.

· Data error (cyclic redundancy check)

· Error 0×80040116

This error message is displayed when you try to access the Deleted Items folder.
