Avoid PST/OST Space Issues: Increase File Size Easily

If you’re running out of space on your PST or OST file, don’t worry! There are several options to increase the file size on your computer. Here’s a guide to help you manage your email storage more effectively.

Adjusting Email Storage on Your Local Computer

One simple solution is to change how much of your email is stored on your local computer. This method works specifically with OST files, which are used for offline access to your mailbox. By adjusting the synchronization settings, you can reduce the amount of data stored locally, freeing up space.

Increasing the Maximum Size of PST and OST Files

If adjusting local storage isn’t an option and you need a PST or OST file larger than 50GB, you can change the maximum size limit by modifying the Windows Registry. Here’s how:

1. Open the Registry Editor:

   • Press Win + R, type regedit, and press Enter.

2. Navigate to the Registry Path:

   • For PST files: HKEY_CURRENT_USER\Software\Microsoft\Office\<version>\Outlook\PST

   • For OST files: HKEY_CURRENT_USER\Software\Microsoft\Office\<version>\Outlook\OST

3. Create or Modify Registry Entries:

   • MaxLargeFileSize: This entry determines the maximum size of the file. Set its value in megabytes (MB). For example, to set the limit to 100GB, enter 102400.

   • WarnLargeFileSize: This entry sets the warning threshold. It should be slightly less than MaxLargeFileSize. For example, set it to 95000 for a 95GB warning.

4. Restart Outlook:

   • After making these changes, restart Outlook to apply the new settings.
