    To prevent data loss during OST migration, start by creating a complete backup of your OST file and ensuring that Outlook is fully synchronized with the mail server. Verify the OST file for corruption before migration and avoid interrupting the process once it begins. For large or orphaned OST files, using a reliable OST migration tool is recommended, as it can preserve emails, attachments, contacts, calendars, folder hierarchy, and metadata. After migration, compare the source and destination mailboxes to confirm that all data has been transferred successfully. Performing a test migration beforehand can also help identify potential issues and ensure a smooth, error-free migration.
