Free PST splitter tools can work sometimes, but they usually have problems and hazards. A lot of free solutions only let you divide a PST file that is very small, or they can fail to preserve the folder structure, attachments, or metadata in the right way. If the process doesn’t go as planned, some free programs can potentially damage your PST file. That is why you should be careful when you use them.
If you want a reliable solution, I suggest utilizing a professional application like DataVare Outlook PST Split Expert Software. It was made to split big PST files without losing or damaging any of the contents. Some of the best features of this software are:
You can split PST files by size, date, year, or folder.
