Yes, you can migrate an old OST mailbox to Office 365 even when the original Outlook or Exchange profile is no longer available. The MailsDaddy OST to Office 365 Migration Tool is designed to access OST files independently and transfer their mailbox data directly to an Office 365 account.
The software can migrate emails, attachments, contacts, calendars, tasks, notes, and other mailbox items while maintaining the existing folder hierarchy and mailbox organization. It also supports orphaned and inaccessible OST files, which can be particularly helpful when an Exchange connection or original user profile is unavailable. With preview and selective migration options, users can review their mailbox data and transfer only the required content, making the overall migration process simple, organized, and efficient.
