I am not able to send emails to one of my coworkers, although for the past 11 months I have been able to. This co-worker shows up in my Lync contacts and I can IM his without any issues. It's only my emails that come back. All other employees in our company can email and IM this person successfully.
Below is the message that comes back when I email him.
Delivery has failed to these recipients or groups:
