Essential Factors for Choosing the Right Software

When selecting a PST splitter tool, it is important to consider several factors that will affect the overall performance and suitability of the software for your needs. These factors include:

1. Ease of Use: A user-friendly interface is important for an easier ride, especially for beginners. The tool must be intuitive and easy to use. Users without much technical expertise need not be confused. An ideal tool should not ask for too many complex steps or configurations.
2. Compatibility: Ensure the tool supports the version of Outlook you are using, including both ANSI and Unicode PST files. A reliable PST splitter tool should be compatible with different versions of Outlook to accommodate a wide range of users.
3. Split Options: Flexibility in splitting options is important. Different users may have specific requirements such as splitting by size, date, folder, or other custom criteria. The more options a tool offers, the better it can cater to your needs.
4. Data Integrity: The preservation of data integrity is one of the most crucial factors when splitting PST files. The tool should maintain the folder structure, metadata, email properties, and other essential elements of the file during the split to ensure that no data is lost or altered.
