I am using Outlook 2000 on both my desktop and laptop, if I send an email to a msn.com address from the desktop it will go through, yet if I send from my laptop I get it returned with the following error message. "A message that you sent could not be delivered to one or more of its
recipients. This is a permanent error. The following address(es) failed". I only get this error when sending to an msn.com address I may have set some sort of security system up with Outlook to stop emails to a msn address, any help appreciated.
