How to Defrag Outlook PST


The Microsoft Outlook program is primarily used as an email client but it also manages calendar schedules, tasks, appointments, notes and more. Data managed by Outlook can be stored locally in a "Personal Folder" or "PST" database file. PST files require periodic maintenance to optimize performance and avoid corruption. Manually compact the PST file used by Outlook to prevent performance issues and loss of data.

  • Microsoft Outlook 2010
  • Name of your Outlook PST data file or Personal Folder

  • Click the "Data Files" tab and then click on the name of your Personal Folder from the list displayed.

  • Click "Settings" and then click the "General" tab. Click the "Compact Now" button.

  • Click "OK" when compaction has completed and click "Close."
