What’s the Most Reliable OST Converter for Large Mailboxes?

[Damari01]

I am dealing with several large OST files (some over 10 GB) and need a reliable OST converter that can handle heavy mailboxes without data loss or corruption. Speed and accuracy are important, and Id prefer a solution that can convert OST to PST and preserve folder structure, attachments, etc.

Can anyone recommend the most trustworthy OST to PST converter tool for large mailboxes? A solution that works well on Windows would be ideal. Also, any tips or precautions during the conversion process would be appreciated.
