Wierd Outlook Email Effect

I was trying to send an email to a new contact today and got the strange message shown below from Microsoft Outlook 2007 as soon as I clicked “Send.”

Searching online for “None of your e-mail accounts could send to this recipient” wasn’t really helpful.  Many of the responses suggested that my email accounts weren’t configured correctly.  Others suggested that the problem was with my ISP.
 
One suggested that the email type of the recipient was “wrong.”  I wasn’t really certain how that could be as the email address had been copied exactly from the forwarded email.
 
With some experimenting, I was able to reproduce the steps that caused the problem.
 
Step 1 – Copy the address as seen in the forwarded email and paste it into a new email.

Step 2 – Click the “Check Names” button to have Outlook convert it to an email address.

 Outlook should have transformed the email address into something like what’s shown next.

Step 3 – Complete the email and click “Send” to send the message.  You should immediately receive the message shown at the beginning of this posting.

What Outlook has done is “helpfully” set the email address type.  Where’s that?  Right click on the address and select “Outlook Properties” to display the properties for the email address.

The “problem” field is “E-mail type.”  Outlook has set it to the custom type of “MAILTO” which it pulled from the address when it was pasted into the new email.

Click the “Internet type” button to change it to “SMTP.”

Once that’s done, the email will send normally to the intended recipient.
