Convert ANSI and Unicode OST Files to PST Files

In today’s globally connected workplace, Exchange mailboxes often contain folder names, data, and character sets shaped by regional languages and domain-specific standards. For example, a user based in Germany may have mailbox folders named in German, with Outlook saving this information in an OST file using localized language settings. When these OST files are converted to PST through Outlook’s native export options, essential components such as Unicode characters or non-English folder names may be altered, omitted, or misrepresented, resulting in an incomplete or inaccurate conversion.

EdbMails OST to PST Converter is specifically designed to address this requirement. It supports both ANSI and Unicode OST files while accurately retaining all language-specific content, including right-to-left languages like Arabic, complex characters from Chinese and Japanese, and special European characters such as ä, ø, and ç. Whether handling multilingual mailbox data from global teams or preserving native formatting during migration, EdbMails delivers a reliable and accurate conversion with no data loss or formatting issues.

In this step-by-step guide, you’ll learn how to add your OST file to the application, let EdbMails scan and evaluate its contents, and export the data into a PST file while preserving the original language settings and folder structure. The process is simple and requires no manual folder renaming or character encoding adjustments, making it an ideal solution for language-sensitive Outlook data recovery and migration.
