MSG files are primarily associated with Microsoft Outlook, so opening them without Outlook can be difficult depending on the operating system. If you only have a few MSG files, you can use an MSG viewer that supports the format. For a large collection, an MSG management or conversion tool may be more convenient. SysTools MSG Converter can be used to access MSG data and convert it into formats such as PDF, HTML, EML, PST, and other supported formats. The right approach depends on whether you only need to read the messages or want to migrate the email data to another application.
