421 = The service is not available and the connection will be closed.
I would contact the email provider to get this resolved.
I am running XP pro and use Outlook Express for email. Suddenly when I try to send messages from OE, I get the error message: server error 421 outlook express. I can , however, receive messages. I have googled for answers but have not been successful in correcting this. This has been going on for 2 days and I'm not able to send messages via OE. Prior to this happening, I was gone and used the wireless feature to access my email. Would there be some connection there? Thank you.
