First, open Microsoft Outlook and import your PST file by going to File > Open & Export > Import/Export > Import from another program or file > Outlook Data File (.pst). After importing, all your emails, folders, and attachments will appear in Outlook.
Next, add your Yahoo Mail account in Outlook. Go to File > Add Account, enter your Yahoo credentials, and configure it using IMAP settings. Once added, your Yahoo mailbox will be visible in Outlook alongside the PST data.
Now, manually drag and drop emails or folders from the PST file into your Yahoo Mail folders in Outlook. Outlook will start syncing this data to your Yahoo account. This step may take time depending on the size of the PST file and your internet speed.
Finally, log in to Yahoo Mail through your browser and check whether all emails have been successfully imported.
However, this manual method has several drawbacks. It is time-consuming, requires Outlook installation, and may lead to missing emails, duplicates, or loss of folder hierarchy—especially with large PST files.
To avoid these issues, many users prefer an easier alternative like the SysInfo PST Converter Tool to import PST to Yahoo. Instead of using Outlook, you can directly add the PST file into the tool, preview all mailbox items, and choose Yahoo Mail as the destination. The tool then transfers emails, attachments, and folder structure automatically, making the process faster and more reliable compared to the manual method.
