Compress Outlook PST files to optimize storage space and improve Outlook performance. The manual process involves reducing the file size by deleting unnecessary items and compacting the PST file. While this method is straightforward, it has challenges. Manual compression requires time and may not achieve significant size reduction if duplicate items or oversized attachments are present. Additionally, there’s a risk of data corruption if the PST file is already close to its maximum size. Managing multiple PST files manually can also be cumbersome. To simplify the process, the Migrate Cloud Data PST Compress Tool offers an efficient solution. This tool automatically identifies and removes unnecessary data, compresses attachments, and reduces file size without compromising data integrity. It also supports batch compression, making it ideal for managing multiple PST files. Using this tool eliminates the risks associated with manual methods and ensures a seamless compression process.
