How can I split a large PST file to prevent corruption in Outlook?

The easiest way to prevent Outlook PST file corruption is to split the large file into smaller, manageable parts using the Advik PST Splitter Tool. Oversized PST files often slow down Outlook or become corrupt, so dividing them helps keep your data safe. With Advik, you just need to install the tool, add your large PST file, and select how you want to split it — by size, year, date range, or folder. Once you start the process, the tool creates smaller PST files without changing your emails, attachments, or folder structure. It works even if Outlook is not installed, and it supports all types of PST files. This ensures your data stays healthy, organized, and fully accessible in Outlook.
