This is one of those keyboards that does not come with Logitech software which leads me to suspect that it gets its information from Windows.
What is your default email application in Windows? What opens when you click a "mailto:" link?
This is what the keyboard tries to launch.
What is your operating system? In Windows 7 there is "Default Programs" in the Control Panel. You might like to investigate that.
I am surprised that anything offers Outlook Express. It was discontinued some years ago.
