Free Outlook autoarchive tool. Split Microsoft Outlook data to multiple PST files.


If you are Microsoft Outlook user for a long time, you know how frustrating it can be to deal with huge amount of data. Large PST files slow down Outlook’s performance and it is hard to stay productive with slow loads of data and avoid constant PST corruption.

The best solution in this case is to automatically split the PST file into smaller Outlook data files and move them to separate Archive files accessible from Microsoft Outlook. You can easily open PST files without Microsoft Outlook using OST PST Viewer tool.

PST Splitter is a free tool to split and archive Microsoft Outlook data automatically. Schedule automatic archiving by date and you can completely forget about it. Data is moved to a new PST file, which is independent and native to Microsoft Outlook. None of the data will be harmed during this procedure. You can easily connect the split PST file to Outlook and access all items in an unchanged form. The PST Splitter Free version gives you the same result as the Microsoft Outlook AutoArchive feature. The difference is - using AutoArchive, Outlook must be open in order to run the archiving process. Using PST Splitter files will be archived according to a schedule regardless of whether Outlook is running or closed.

Effectively manage Microsoft Outlook data files using PST Splitter Pro Edition. It enables you to split Outlook data manually by various criteria, such as size, folders and accounts. Archive unnecessary folders of old projects and move them from existing PST to a new one, or just copy data to have it in both places. Reduce the size of your PST file, avoid reaching 2GB limitation and increase Outlook performance.
