Summary: Handling issues in MS Outlook, especially PST file corruption is difficult if you are not aware of the solution. It is yet more difficult when the inbuilt utilities fail to rectify the issues. Once such instance is Outlook cannot open PST file after repair. Nevertheless, with the right knowledge and acumen you can address the problems.

Consider a scenario: A user installed and configured Outlook 2007 on his brand new system running Windows 10 operating system. Next, the user imported old Outlook 2003 (PST) data file in the newly installed and configured Outlook 2007, as all the old Outlook data was important and the user needed those all. For a while, the import seemed successful as the user could access all imported data; however, after some time he encounters Archiving and Personal Folders issues in Outlook.

Having the basic knowledge of Outlook, he assumed that the Outlook profile was corrupt. Therefore, he created a new Outlook profile, and tried to open old Outlook (PST) data file as well as import the PST file. But he failed again!

Further, trying to understand the issue and figure out a solution through Google, he realized that the issue was damaged PST file and the reason for damage was large size PST file. As suggested by different users, he used the ‘Outlook Cropping Tool’ to reduce PST file size. He also used the Inbox Repair Tool (scanpst.exe) to repair corrupt Outlook PST file.

After executing these two tools, he again tried opening the PST data file in Outlook and failed again. He could select the PST file but could not perform any function on this PST. He was not allowed to load PST file. On trying to import the PST, he encountered the error: “the messaging interface has reported an unknown error. If the problem persists, Restart Outlook.” This showed that neither the Inbox Repair Tool nor the Outlook Cropping Tool that he used gave desired results, because of the limitations attached with both Inbox Repair Tool and Outlook Cropping Tool, the inbuilt utilities of MS Outlook.

  4. Requires knowledge of the entire file repair process including location of scanpst.exe as well as PST file location depending on Outlook version
  5. Scantpst.exe is an eight phase process which may pause/terminate before completion, due to virus/malware attack or attack by other malicious code
  6. In some cases, the tool displays an error messages and fails to repair severely damaged PST files
