If you want to import PST files to Office 365, you can do it smoothly using the SysInfo PST File Converter, which supports direct migration to cloud accounts. After launching the tool, you add your PST file and review its contents in the preview window. Then you select Office 365 as your target platform and log in securely through OAuth authentication. You can choose only the folders you want or apply filters such as date range, duplicate removal, or attachment settings. When you start the import, the tool transfers all selected emails, calendars, contacts, journals, and notes into your Office 365 mailbox while keeping the original folder order. Once the transfer completes, your PST content appears in Office 365 exactly as it was in Outlook.
