If you want to move your OST file emails to Office 365, the Sysinfo OST to PST Converter makes it super simple. Just open the tool, upload your OST file, and pick Office 365 as your destination. Log in to your Office 365 account, and the software will directly transfer all your OST data — emails, attachments, contacts, and more — into your Office 365 mailbox safely. You don’t need to install Microsoft Outlook, and all your folders will remain properly organized after the import.
