Microsoft Outlook stores all mailbox data in PST files. Over time, these files can grow too large, leading to performance issues or corruption. To avoid this, users can split their PST files using either free manual techniques or professional tools.
Free Method (Manual):
Outlook does not offer a direct "split" option, but you can use the Import/Export feature or Archive option to create multiple smaller PST files. For example, you can archive emails by year or by folder to separate PST files. This method is free but requires time and effort, especially if you need to split large files or maintain folder structure.
Professional Method:
For a faster and more accurate solution, tools like MailsDaddy PST Split Tool allow users to split PST files by size, date, folder, or email ID. These tools preserve data integrity and support both ANSI and Unicode PST formats without requiring Outlook installation. You can split large PSTs (even over 50GB) in just a few clicks.

Whether you're managing personal emails or handling corporate data, choosing the right method ensures better Outlook performance and data safety. The manual option works for occasional needs, while professional tools are ideal for bulk or regular PST management.
