Extract text from MSO files
To convert your MSO file to another format, you need Microsoft Outlook or other Encoded software.
To convert other file formats to the "Email Attachment" file type, you need software like Microsoft Outlook or a similar tool.
The .MSO file extension is primarily associated with the Microsoft Office OLE Data format, most commonly encountered as the attachment oledata.mso. These files are automatically generated when a user sends an HTML-formatted message using Microsoft Outlook or saves an Office document as a web page. The file acts as a proprietary container that stores Object Linking and Embedding (OLE) information, enabling Microsoft Word to re-render the document with full fidelity - including macros and complex formatting - if it is opened again in the original software.
For the recipient, .MSO files present significant usability challenges. Because they are encoded strictly for Microsoft's internal use, they appear as unreadable attachments to users on non-Microsoft email clients (such as Gmail, Thunderbird, or Apple Mail) or those without Office installed. They cannot be opened by double-clicking and often trigger security concerns due to their obscure nature. Furthermore, they can bloat email sizes without adding visible value to the standard message text. To access the content locked inside these files - often equations, vector graphics, or styling data - users should extract the data or convert the file.
Convert.Guru analyzes your MSO file, detects the exact format, and lets you read the text inside.

The history of Convert.Guru began over 25 years ago in California with Tom Simondi’s file-format database. A former contributor to Space Shuttle development and a software pioneer of the 1980s, Simondi established a trusted resource for file type analysis that was even referenced by Microsoft Windows XP. Today, we use modern technology to process and convert thousands of file formats while continually improving our MSO converter.
