PST files, denoted by the .PST extension, store a comprehensive dataset within MS Outlook, encompassing emails, contacts, tasks, and more. Over time, these files can accumulate a substantial volume of email messages, leading to increased file size. As a consequence, MS Outlook may begin to experience frequent crashes, ultimately resulting in PST file corruption. Such corruption directly translates to data loss, potentially causing distress and frustration due to the damage inflicted on critical information.

Hence, IT professionals strongly recommend that Outlook users regularly back up and archive their PST files. Daily data backups are essential for ensuring data security and safeguarding against potential corruption issues. As a result, older emails are archived to reduce the size of PST files, with these historical emails being stored in a designated ‘Archive.pst’ file.
