Many Outlook users end up with one or more OST files after changing computers, deleting an Outlook profile, switching email accounts, or moving to Microsoft 365. Although these files still contain valuable mailbox data, accessing or transferring that information is not always straightforward. If you need to Import OST Files to Office 365, choosing a reliable migration method can help avoid data loss, skipped folders, or incomplete mailbox transfers.
A successful migration should preserve emails, attachments, contacts, calendars, tasks, notes, journals, folder hierarchy, and email properties while ensuring that the destination mailbox remains organized.
