How do eml files open?

Microsoft's own Outlook mail program is available on general Windows XP systems, and you can use it to open eml files.

Open step: Outlook Express. In general (when the system default mail handler is Outlook Express), it opens by Outlook Express, or you can right-click on the file to select: Send to-> Mail recipient, ok! of course, You can also open OE5 and set the window to a regular size, and then drag the eml file to the OE Inbox and release the mouse.

If you don't have Outlook Express, you can change the. eml file extension to. htm, and try it on IE, sometimes open it. If not, you can only install Outlook Express to try.
