Stellar PST Splitter is a useful app that efficiently splits a large PST file into smaller and manageable PSTs, based on specified PST split criterion, such as Date, Size, Mail Id and Folder.

Key Features include:

• Splits PST files into smaller ones and helps avoiding PST corruption.
• Split PST by Date, Size, Mail id, Folder etc.
• Performs splitting operation on a newly created PST file, original PST remains intact.
• Preserves the structure of original PST files after splitting.

The trial offers only two PST splitting options, i.e. 'By Size' and 'Select and Split'. In order to use other features of the app, you need to register the product.

If you are looking for a straightforward app, designed to help you create multiple .PST files from your Microsoft Outlook data, then Stellar PST Splitter is a good option. The interface is rather dated and some would consider the options limited, but it performs .PST file splitting adequately.
