Outlook Error 421
« on: February 09, 2012, 08:40:14 PM »
Outlook 2007 keeps giving me the following error message when sending an email. The Server responded 421..I turn off scan outgoing messages in the mail shield and the error goes away and the messages are sent with no problem...Turn it back on and the error returns. Any direction on resolving this would be great...
