If youre searching for a free download of Outlook PST Splitter software, MSOutlookHelp offers a reliable tool that helps you easily split large PST files into smaller, manageable parts without any data loss. You can download the free version directly from their site at www.msoutlookhelp.com/pst-splitter/. For those who prefer a manual method, you can reduce PST file size by creating a new PST file in Outlook and moving or archiving emails and folders into it, but this approach is time-consuming and less practical for very large files. Using the MSOutlookHelp splitter software is a faster and safer solution.
