Cannot send emails from outlook.com or Mail App

HI All,

I have just started using the Mail App in Windows 8 which has been configured to my Outlook ID.

I was able to use it until about a couple of days ago for sending emails.

A couple of days ago it asked for verification before sending emails, I verified the phone number and alternate email address.

Now, my emails do leave the outbox but aren't received.

On the other hand, I can receive emails.

I also tried sending emails from the outlook.com website, no luck there either.

Can anybody help!

Regards,

Zeba
