.mso - Microsoft Office Rendering Data
The MSO data files are related to Microsoft Office Outlook 2000 (or above). MSO file is a Microsoft Office Rendering Data. When sending HTML messages with an attached Microsoft Office document, the message is sent as an Outlook HTML message, not an Office Envelope message. The Oledata.mso file contains necessary information to properly render the attachment in the message in its originating program. If an HTML message is opened on a computer that does not have Outlook 2000 installed, you will see the Oledata.mso file as an additional attachment.

Can't open a .mso file?
When you double-click a file to open it, Windows examines the filename extension. If Windows recognizes the filename extension, it opens the file in the program that is associated with that filename extension. When Windows does not recognize a filename extension, you receive the following message:
Windows can't open this file:
To open this file, Windows needs to know what program you want to use to open it. Windows can go online to look it up automatically, or you can manually select one from a list of programs that are installed on your computer.
To avoid this error, you need to set the file association correctly.
- Open Control Panel > Control Panel Home > Default Programs > Set Associations.
- Select a file type in the list and click Change Program.
