Introducing an Outlook storage extension script that solves the problem of limited inbox storage. While we may not be able to get you to Inbox Zero, this script increases your storage capacity so that you can fill up your inbox worry-free.
By default, Microsoft Outlook has a size limit on its Personal Storage Table (PST) files, which can cause problems when you receive a lot of emails. This script is a Windows command line tool that raises this limit, allowing you to store more emails without worrying about hitting the threshold.
The script achieves this by modifying two Outlook settings that control the size limits. The first setting establishes a warning threshold that notifies you when you’re approaching your storage limit, giving you ample time to manage your email storage. The second setting defines the maximum size that your PST files can reach before they become unstable.
Using this script will help you manage your email storage more efficiently and avoid any issues that may arise from exceeding the default size limits.

REG ADD "HKEY_CURRENT_USER\Software\Microsoft\Office\16.0\Outlook\PST" /v WarnLargeFileSize /f /t REG_DWORD /d 95000 REG ADD "HKEY_CURRENT_USER\Software\Microsoft\Office\16.0\Outlook\PST" /v MaxLargeFileSize /f /t REG_DWORD /d 100000
Will the script cause any data loss or corruption to my email data?
While the script is intended to increase the storage capacity of your PST files, it’s always a good idea to back up your data before making any changes to your Outlook settings or PST files.
Does the script work with Office 365 and other cloud-based Outlook versions?
Because cloud-based versions of Outlook, such as Office 365, use different storage mechanisms than traditional PST files, the script may not be compatible. To ensure compatibility, consult the documentation for your specific version of Outlook.
Can the script be run on a shared or network drive?
No, the script should be run directly on the device where Outlook is installed. Running the script on a shared or network drive may cause issues with the registry modifications.
- Before running the script, you must determine which Outlook version you have installed. To do this, launch Outlook and navigate to File > Office Account > About Outlook. The build version of Outlook you are running will be displayed. Once you have identified your version of Outlook, modify the script by replacing ‘16.0’ with the appropriate version number (14.0, 15.0, or 16.0) to ensure compatibility.
- Admin permissions are needed to run this script.
- After running the script, it is necessary to restart your device for the changes to take effect.
- WarnLargeFileSize – This registry value is set to 95000 in decimal format (equivalent to 95GB) which represents the size limit threshold for PST files before Outlook issues a warning.
- MaxLargeFileSize – This registry value is set to 100000 in decimal format (equivalent to 100GB) and represents the maximum size limit for PST files that Outlook will allow before they become unstable
- /f – This specifies that any existing registry value with the same name should be overwritten.
- /t REG_DWORD – This specifies that the data type of the registry value is a DWORD (a 32-bit unsigned integer)
