I use outlook 2010 and when I send an email and use the address book it won't send. I get the screenshot message attached. This is how it is. When it start to type an email address it will come up with Jon Doe. Jon Doe's email address is firstname.lastname@example.org. This will not send it get the message. If I type in email@example.com it will work fine. Any ideas? Must be something with my address book.
