When Outlook is not available, accessing OST files can become a challenge. A dedicated OST to PST Converter allows users to Convert OST to PST without Outlook, making mailbox data accessible without dependency on the original setup. The tool supports multiple formats including EML, MSG, MBOX, HTML, PDF, EMLX, and MHTML, offering flexibility for data storage and sharing. The OST to PST Conversion process ensures that attachments, folder hierarchy, and metadata remain unchanged. Contacts can be extracted into VCF format, enabling seamless transfer between devices or applications. Calendar entries can also be exported into ICS format, preserving important event details. This ensures that all mailbox data remains intact and usable.
