If you're tired of Outlook Express launching whenever you click an
email file or a forwarded message in IncrediMail, here's how to make
these .eml files open in IncrediMail automatically
When you save a single email message in IncrediMail, it will be in
Mail format, and the extension of the file will be .eml. If somebody
forwards you an email as an attachment, the forwarded email will
arrive in just this .eml format.
Now, if you double-click on any of these .eml files (in Windows
Explorer, IncrediMail or elsewhere), chances are the message will
open in Outlook Express -- annoying if you use IncrediMail for all
your email and have made it your default email program, too.
Fortunately, it's easy to make .eml files open in IncrediMail so you
can happily double-click them and don't have to read forwarded
emails in a program you didn't ask for.
To associate IncrediMail with .eml files:
1. Select Tools | Options... from the menu.
2. Go to the Advanced tab.
3. Make sure Associate '.eml' files with IncrediMail is checked.
4. Click OK.
