The two work-arounds I found:
1. Install MS Outlook; WLM will pick up it's MAPI engine, it seems.
2. Save the scanned file to disk and send it as an attachment.
Don't confuse MAPI and pop3.
- MAPI has to do with the way the mail functions are called from inside your computer.
- pop3 has to do with the way your mail client is 'talking' with your ISP

I have used my Epson scanner Perfection 4490 Photo, and Earthlink.net with all the last three versions of windows,Using:(pop3.earthlink.net)and (smtpauth.earthlink.net)and Scan to Email worked perfectly.
I now have Win 7 KUltimate and when the Scan to E-mail button is selected I get the little window: "The supported E-mail program is
not installed,. Install the E-mail progam and try again.:
All other scanner buttons work perfectly.
I emailed Epson Tech support, explained the problem and received the following reply"
From Epson Tech support:"Your email app must be a MAP-I based program. If Windows Live is web based it will not work"
How can I make my Earthlink.net a MAP-I based program. Can I safely replace the pop 3 with MAP-I,without fouling up anything,and/or how will this effect my earthlink.net mail?
