A PST file, short for Personal Storage Table, is a type of file used in Microsoft Outlook. It serves as a personal folder where users can store emails, calendar events, contacts, and other data. The maximum storage limit for a single user's PST file in Outlook is generally 2GB. When functioning as a cache for Outlook's Cached Exchange Mode, which allows users to work offline with their email data, the file is referred to as an Offline Storage Table (.ost) or an Offline Folder File. This feature enables users to access their emails even when they are not connected to the internet or the Exchange server, as it stores a local copy of their mailbox content.

When you delete a device's PST file, the data is not actually erased. The operating system becomes unable to access the associated data since the entries for those files have been removed. It categorizes the sectors occupied by the prepared data as free space. New data is then written over these recently designated areas.

    1. Regularly back up essential files, including the PST file, and store them on an external hard drive. 2. Scan your computer for viruses using antivirus software. 3. Be cautious not to accidentally delete files. 4. Avoid using "Shift+Delete"; instead, use the "Delete" key or right-click and select Delete. 5. Do not abruptly terminate Microsoft Outlook.

3. How do I retrieve PST emails? To retrieve emails from a PST (Personal Storage Table) file, follow these steps: 1. **Download and Install a PST Viewer Tool**: Since Outlook is required to access PST files, ensure you have Microsoft Outlook installed on your computer. If not, you can use a free or paid PST viewer tool, such as Stellar Phoenix Mailbox Exchange Recovery, or Outlook Import Wizard. 2. **Locate the PST File**: The PST file usually contains all your email data.
