For some reason I'm not able to receive any hotmail emails. We have an exchange server that catches all domains. It was working till yesterday. Nothing has changed. Have checked the firewall logs. Everything is ok. My collegue is able to get his emails from hotmail. We can sent it out though. Is there anything I can do internally to test and how do I solve this problem. I've resent the email from my hotmail and gmail account to firstname.lastname@example.org Been sitting for over an hour and still not received it.
