Apparently, WL Hotmail does a check every so often to make sure you're human. I think this is something new that started in the past month, because I've been prompted online and when using WL Mail (formerly known as WL Mail desktop). Actually, the latter situation is exactly the problem I ran into.
When using Windows Live Mail (formerly known as WL Mail desktop), you receive an error message that is similar to the following when you synchronize (send/receive) accounts:
The message could not be sent. Subject: '<message subject>', Protocol: HTTPMail, Server Response: 'There is an error synchronizing your mail account. Please verify your account has been configured correctly by first accessing your mail on the web.', Port: 0, Secure(SSL): No, Server Error: 0x80AA4193, Error Number: 0x80AA4193
WL Hotmail added checks to validate that you're a human. The error message is essentially letting you know that Hotmail won't allow you to send email until you verify you're human. You can, however, receive email.
As the error message claims, you need to login to your email server on the web. Unfortunately, what isn't specified is that you have to login to hotmail.com and not mail.live.com. Most people will never run into this because I believe most people are old Hotmail users that login via the hotmail.com website. If you don't, tho, you'll have to do it at least once to get past this issue.
Edit: I just found out that upgrading to the newer release of WL Mail should also fix the problem. Obviously, this is the recommended long-term fix. I won't get into the details of it, but the new version is supposed to allow you to verify you're a human without having to login to the website and, additionally, requires these checks less due to improved logic.
