OST (Offline Storage Table) files are created by Microsoft Outlook and are used to store emails, contacts, notes, calendar items, and other Outlook data on a local computer. OST files are not compatible with other email programs and cannot be opened directly. To open an OST file, it must first be converted to a different file format, such as PST (Personal Storage Table) or MBOX (Mailbox).
Converting an OST file to another file format can be done using various software applications. It is important to note that some OST files may be corrupted or encrypted, which can make conversion difficult or impossible. Additionally, OST files can become large and difficult to manage, which can lead to performance issues and data loss.
For these reasons, it is recommended to use a free and easy online website, such as Convert.Guru, to convert OST files. Convert.Guru offers fast and secure conversion of OST files to PST, MBOX, EML, and other file formats, making it easy to open OST files in other email programs.

Today, we use modern technology to process and convert thousands of file formats while continually improving our OST converter.
