Split Outlook Store
Split Outlook Store is a utility designed to divide large Outlook mailboxes, data files, and other stores into several smaller PST files. This tool addresses the challenge of managing oversized Outlook data, which can impact performance and complicate archiving or migration tasks. It preserves the original folder structure and creates complete copies of all elements, including messages, tasks, calendar items, notes, journal entries, contacts, and items from folders such as Inbox, Sent Items, and Deleted Items.
The utility offers segmentation of source data files by size and year, allowing for granular control over how new PST files are generated. Users can specify a maximum file size, a particular year, or both, resulting in multiple files organized according to these criteria. Split Outlook Store supports both modern Unicode and legacy ANSI data files, ensuring compatibility with a wide range of Outlook versions and data formats. When splitting, the original data files remain unchanged, and all recipients, attachments, formatting, and other fields are retained in the new files.
Split Outlook Store can be run as a stand-alone application through the OutlookFreeware Utility Manager. There is a free limited version available for download, intended for non-commercial home use only and not functional in domain environments. Certain advanced features, such as batch mode for processing multiple files across various locations and network resources, are available to Professional Edition owners. An advanced version is also included in ReliefJet Essentials for Outlook, a commercial product.
The tool is compatible with Microsoft Office Outlook versions 365, 2021, 2019, 2016, 2013, 2010, and 2007, and runs on Windows operating systems from XP SP3 through Windows 11. Its integration with Outlook is optional, and the free version may include additional limitations compared to the advanced edition. Split Outlook Store is particularly suited for home users seeking to improve Outlook performance and manage large or aging data files more efficiently.
