Excluding Microsoft Outlooks's .pst file from real-time scanning

If you have set real-time scanning to scan all files, you might want to exclude Microsoft Outlook’s .PST file from the scanning in order not to slow down the system unnecessarily, as PST files are typically very large and take a long time to scan.

The .PST file is excluded from scanning for the whole domain as follows:

  1. Select Root on the Policy domains tab.
  2. Go to the Settings tab and select the Real-time scanning page.
  3. Select the Enable excluded extensions check box.
  4. Enter the extension PST in the Excluded extensions text box. Note that the extension should be added without the preceding . (dot).
  5. If you want to restrict users from changing the settings, click the lock symbol beside the settings.
  6. Click to distribute the policy.
