What is a .MBX file?

The file extension .MBX represents a type of file known as an Outlook Express Mailbox. This type of file is used specifically by the email program Microsoft Outlook Express, which has now been discontinued. An .MBX file functions as a mailbox or mail folder, storing actual email messages that have been received or saved in Outlook Express.

The content inside an .MBX file includes the complete data of the email messages, such as the text of the emails, sender and recipient information, and the date the emails were sent. These files are crucial for users who want to keep a backup of their email communications. To create a backup, users can simply copy the .MBX files from their original location to a different folder or storage device.

Although Microsoft Outlook Express is no longer available, there are still ways to open .MBX files. One such method is by using a program called Aryson MBOX Viewer. This software allows users to view the contents of .MBX files without the need for the original Outlook Express program. This can be particularly useful for accessing old email archives stored in .MBX format.
