To convert EML files to PST manually, you can import EML files into Outlook via drag-and-drop or use Windows Live Mail and Outlook together. However, this method is time-consuming and lacks bulk conversion support. Alternatively, the DRS Softech EML Converter Tool seamlessly converts EML to PST in bulk without any data loss. It maintains the original folder structure, supports all Outlook versions, and allows previewing emails before conversion. The tool is user-friendly and ideal for both technical and non-technical users.
