My organization's email is being hosted by Network Solutions, however, we are using our Exchange Server to manage emails. All of a sudden we aren't able to receive external emails. We can send out external emails but can't receive them. Please help!!!!!

Hi, Did you tried to test it here? https://testexchangeconnectivity.com/Regards from www.windowsadmin.info

I tried that specifically, I tried the internet email test. Was the right one? What's odd about the problem is that it's only affecting one email address on the network.

After checking the event viewer, I found the following error message The TCP/IP connection with the 'localhost' server was terminated while trying to access the 'username@parents4publicschools.org' mailbox. The cause may be server problems, network problems, a long period of inactivity, a connection time limit, or incorrect connection settings. What does this mean?

Hi, Did you checked whether the Receiving Connectors are working perfectly? Exchange Management Console ->Server Configuration ->Hub Transport In the bottom right pane the Receive Connector tab should already be in front You should see "Default (your server name here)" If it is perfect, check with your firewall settings for any block for inbound messages Another thing is your ISP settings. Contact ISP and confirm that their part is okay Regards from www.windowsadmin.info
