Very large PST files can increase the chances of Outlook crashes, data corruption, and even the risk of losing important emails if the file becomes unstable. SysInfo PST Splitter Tool helps reduce these problems by splitting large PST files into smaller and more stable files without affecting the original data. One useful feature is the Split by Sender option, which allows users to organize emails based on different sender email addresses. This makes it easier to manage conversations and quickly find emails from specific contacts without searching through the entire PST file. Another important feature is Password Protection, which allows users to secure the newly created PST files with a password. This ensures that sensitive email data remains safe and protected from unauthorized access. Additionally, the tool provides a Flexible Save Location option, which lets users choose any desired location on their system to store the split PST files. This helps in better file management, easy access, and proper organization of Outlook data, making daily email handling more efficient and smooth.
