An attempt was made to access a socket in a way forbidden by its access permissions

When setting up the Microsoft Dynamics Email Router, there can be a lot of obstacles in getting emails to send and receive properly. One of which turns out to be McAfee VirusScan. If you get the following error when testing the connection on the Outgoing profile, you may want to see if McAfee (or any other virus protection software) is running on the server:

Outgoing Status: Failure – An error occurred while checking the connection to the email server {smtp server name}. An attempt was made to access a socket in a way forbidden by its access permissions.

In order to fix this, right click on the McAfee icon in the system tray and open up the VirusScan Console.

In the VirusScan Console, double-click “Access Protection”.

Under Categories, click on “Anti-virus Standard Protection” and then check to see if there are any checkmarks next to “Prevent mass mailing worms from sending mail”. If there are, simply uncheck them.

Click OK and close out of the VirusScan Console. Open the email router and try testing again. You should now be seeing green!
