OST files can be converted to PST format using either manual approaches or specialized software. For a manual method, you could import an OST file into Outlook with the Export feature, integrate OST data into Outlook for free via the Archive function, or create a new PST file to combine OST contents within Microsoft Outlook. However, these self-managed techniques are often time-intensive and demand technical expertise.
For a faster and more trustworthy solution, the SysInfo OST to PST Converter Tool excels as a tailored application that converts OST files to PST format while ensuring full data accuracy and security. It supports transforming OST files into multiple formats, such as PST, MBOX, EML, EMLX, HTML, CSV, and MHTML, offering flexibility to meet varied user preferences. The tool facilitates batch processing of one or several OST files and smoothly migrates OST components—like emails, contacts, calendars, tasks, and notes—to over 15 online and cloud-based email services, including Office 365, Gmail, Thunderbird, and Yahoo Mail, delivering an efficient and seamless data migration experience.
