| Description | The MSG file extension is a Microsoft product used for messaging in Outlook mail. It was created to manage email communication for Microsoft users. An MSG file is generated each time a message is composed using Outlook, containing important information from the email sent and details about the message. Programs that can open such files are typically compatible with the Microsoft Messaging Application Programming Interface. |
| Technical details | MSG file is a complex text file that contains all the information but cannot be viewed using Notepad or other word processing programs. The message is created using a binary format, and compatibility with programs depends on whether it has a MAPI system. This unique file format makes it impossible to import into other email services. The creation of this file format is automatic upon executing a function, such as saving a message. |
