If you need to split an Outlook PST file without losing data, first create a backup of the original PST and keep it unchanged until you verify the new files. For a large PST, manually moving emails can be time-consuming and may make it harder to maintain the original folder structure.
A dedicated PST splitter can help divide a large Outlook PST file based on your requirement. For example, GainTools Split PST provides options to split PST by size, year, or folder. This can be useful if you want smaller PST files by a specific size, separate older and newer Outlook data, or divide selected folders.
It supports ANSI and Unicode PST files. After splitting, open the resulting PST files in Outlook and verify emails, attachments, folders, contacts, and other required items before removing the original PST.
