Best method to break large PST files in Outlook

[Anand-Kashyap]

The best method to break large PST files in Outlook is using a PST splitter tool like Regain PST Splitter. It allows you to divide large files into smaller, manageable parts without risking data corruption. You can split by size, date, or by sorting emails by sender, recipient, or subject. Another option is using Outlook’s AutoArchive feature to automatically move older emails into separate PST files, reducing file size over time. Alternatively, you can manually move emails to new PST files based on specific criteria, or use the Compact tool to reduce file size by removing unnecessary data. However, a PST splitter tool is the most efficient and safe method for managing large Outlook files.
