EdbMails is a reliable software solution for recovering EDB files and exporting mailbox data, including emails, contacts, calendars, and journals, to PST format. One of its key features is the ability to split large EDB mailboxes into multiple PST files based on a size you define.
This splitting process ensures better manageability and prevents performance issues that can occur with oversized PST files. Each PST file generated can be opened and viewed separately in Microsoft Outlook, giving you flexible access to your mailbox data while keeping file sizes under control. With EdbMails, you can perform this operation seamlessly during export, maintaining data integrity and folder structure throughout.
Why You Should Split Large EDB Files
Large EDB files can slow down Exchange Server, make backups take more time, and raise the chance of database problems. Splitting them into smaller PST files can speed up performance, lower risks, and make mailbox data easier to handle.
- Avoid EDB mounting issues – Oversized EDB files are more prone to mounting failures. Splitting them helps maintain database stability and ensures smooth accessibility.
- Faster mailbox backup and restore – Smaller PST files are quicker to process, saving time during backups and recovery operations.
- Improved Exchange Server performance – Reduces server load, leading to faster mailbox access and better overall responsiveness.
- Easier archiving and sharing – Manageable file sizes make it simpler to store, transfer, and share mailbox data when needed.
- Minimized risk of data loss – In case of corruption, only a smaller PST file is affected instead of the entire EDB database.
- Selective data export – Split and export only the specific mailboxes or items you require, keeping your data organized and relevant.
