Questions and answers

  • What is the purpose of ".OTLN Recovery" and how does it work?

    ".OTLN Recovery" is a file extension used by Microsoft Outlook to store recovered items from corrupted or damaged Outlook data files. When Outlook encounters issues with its data file, it automatically creates a new file with the ".OTLN Recovery" extension to salvage as much data as possible.

    The purpose of ".OTLN Recovery" is to provide a means of recovering important data from a damaged Outlook data file, such as emails, contacts, calendar entries, and other items. It acts as a temporary storage for recovered items until they can be merged back into the original data file or a new data file is created.

    The recovery process in Outlook involves the following steps:

    1. When Outlook detects a problem with a data file, it creates a new file with the ".OTLN Recovery" extension.
    2. Outlook scans the damaged data file and attempts to recover as much data as possible.
    3. Recovered items are stored in the ".OTLN Recovery" file.
    4. Users can access the recovered items through the "Recovered Personal Folders" section in Outlook.
    5. Users can review the recovered items and manually move them back to their original folders or other desired locations.
    6. Once the recovery process is complete, the ".OTLN Recovery" file is typically deleted, and the original data file is either repaired or replaced.

    It's important to note that the ".OTLN Recovery" file is a temporary solution and not a substitute for regular backups. It is always recommended to maintain regular backups of Outlook data to prevent data loss and minimize reliance on recovery mechanisms.
