How can I get Excel to use Outlook when I go to the send to option
 

Before, I could go to the send to option in Excel and when I click on Mail
Recipient, it would use Outlook as the email program. Now it goes to
Yahoo.com to send it which I do not want. It causes more time to open up
outlook, find the attachment, and then send it when I could simply use the
send to command. I've already sent Outlook as the default email program and
it still wants to use yahoo. Any suggestions?
