Windows Security window preventing outgoing email

[Guest]

When attempting to send an email a “Windows Security†window pops up asking
for my user name and password. I have no idea why this window pops up as my
incoming and outgoing mail settings are correct and the remember my password
box is checked in the tool settings. This is new Vista operating software. I
know the setting are all correct as my email was working great for a while
but now out of no where the Window Security window appears and rejects my
user name or password when entered. I tried upper and low case. I cannot get
past this window. Oddly enough I am able to receive emails.

Which antivirus are you running?
Windows Mail is not compatible with most McAfee or
Norton security programs. Those will need to be
uninstalled, not just disabled.

After uninstalling your non-compatible antivirus, download
and install a more compatible antivirus like the free Avast:

Even compatible antivirus programs will need to have their
email scanning option turned off. For more on this topic see
