Make sure you are not using incompatible third party security
software. 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
