I am using Microsoft Outlook and currently have multiple OST (Offline Storage Table) files containing important emails. Due to a system crash and mailbox migration, I need to convert these OST emails into MSG file format so that I can access individual emails and share them easily. I tried exporting data from Outlook, but it only supports PST export and not direct OST to MSG conversion. I am specifically looking for a safe and reliable way in 2025 to convert OST emails to MSG format without data loss, while preserving email properties like subject, sender, attachments, and timestamps. Can anyone suggest the best approach or tool to convert OST to MSG files efficiently?
