Resolving "Email Checksums Scan Failed" Error in eDiscovery Platform

Problem

Users encountered an issue during a restore operation from a backup created in version CW10.0 to version 10.2.7 of the eDiscovery Platform. Specifically, when attempting to perform a checksum update, the process failed with the error message: "FAILED: The mail file does not have write access for current user." This issue persisted despite ensuring that all relevant folders, including the "convertedfiles" folder and source folders, had "Everyone" modify rights. The problem disrupted the checksum validation process, potentially impacting the integrity of email data restoration.

 

Error Message

"FAILED: The mail file does not have write access for current user."
This error indicates that the system was unable to write to the specified mail file due to perceived permission restrictions, even though folder permissions were configured correctly.

 

Cause

The root cause of the issue was related to corruption or inconsistencies within the mail files being processed. These inconsistencies prevented the checksum update operation from completing successfully. While folder permissions were correctly set, the underlying issue was with the integrity of the mail files themselves.

 

Solution

To resolve the issue, the following steps were taken:

1. Run Scan PST Tool: The Scan PST tool was executed on the problematic mail files. This tool is designed to identify and repair corruption or inconsistencies within PST files.
2. Repeat Until No Errors: The Scan PST tool was run iteratively on the affected files until no further errors were reported. This ensured that all corruption issues were resolved.
3. Reattempt Checksum Update: After repairing the mail files, the checksum update operation was retried, and it completed successfully without further errors.
