The SYSessential OST to PST converter is a utility that can convert your original OST file to a new PST file while retaining all original data. The transfer of all components (including email, calendar appointments, and tasks) will be secure, with the source file hierarchy preserved. Throughout the conversion process, all mailbox components remain organized, and the metadata (formatting) is retained. The entire process is completed completely and accurately, so you will still be able to access your data after it has been converted to a PST.
