    My outbox has messages in them and they will not send. These were test
    emails to see if all is working properly.

  6. Change the outgoing server name to, and make
    sure you have send authentication enabled: Tools, Accounts, select
    that account, Properties, Servers. Check the "My server requires
    authentication" box.

    If no improvement (same error message), which antivirus are you
    running? Some of them cause problems with Windows Mail over time.

    I also have the same problem, i have followed your advice and am led to beleive that it is my virus/spyware. I am running AVG and Spyware terminator. I have updated these but unsure what else i would need to do to them to get my email up and running.

    All help gratefully received.
