How to Backup Outlook OST File - Expert Tips

To back up an OST (Offline Storage Table) file in Microsoft Outlook, you can use either manual or automated methods. Here’s a concise guide to help you complete this task effectively:

Method 1: Manual Backup of OST File

  • Ensure Outlook is not running before proceeding.
  • Open File Explorer and navigate to:
    C:\Users\<YourUsername>\AppData\Local\Microsoft\Outlook\
  • Alternatively, type %localappdata%\Microsoft\Outlook in the File Explorer address bar to access the folder directly.

Find the file with the .ost extension corresponding to your account and copy it to a secure backup location, such as an external drive, cloud storage, or another folder.

While OST files store mailbox data for accounts using Exchange, IMAP, or Outlook.com, they are server-dependent and may not function properly when moved. For a more reliable backup, exporting the data to a PST file is recommended. The PST format ensures data portability and usability independent of the server.

Method 2: Using a Tool for OST to PST Conversion

Since OST files are tied to specific account configurations, converting them to PST format is often necessary for migration or backup. Tools like Cigati OST to PST Converter offer an efficient and straightforward solution for this purpose, allowing you to secure your mailbox data in a universally compatible format.
