How do I repair a corrupt PST file?

PST files are often used to store copies of messages, calendar events and other similar items. They are particularly unreliable and vulnerable to corruption, which sometimes results in the loss of valuable data. In addition, the time it takes to resolve problems with PST files can represent a significant loss of resources for IT administrators.

PST files are created using the Microsoft Outlook desktop client. They are used to store local copies of emails, calendar events, contacts, to-do lists and other similar items.

Each PST file is a container that contains a folder structure and a set of individual elements. Since emails and attachments are often quite large and some PST files contain many elements, these files can sometimes reach several GB each. The maximum size allowed for a single PST file is 50 GB.

PST files can be corrupted for several reasons. A PST file can be corrupted if it is opened in Outlook when the application exits early. This can happen if Outlook or Windows fails, or if the computer shuts down without leaving Outlook and Windows normally.

Usually, this problem is caused by a sudden shutdown of the application without saving the data. It can also be caused by a system crash or power failure. Finally, it may be caused by exceeding the 2GB size limit. PST files can also be damaged by malicious infection or other viruses.
