If you are sure that you have entered the correct username and
password, then you could be experiencing account corruption
caused by your antivirus program. Windows Mail is not compatible
with most McAfee and 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

If after uninstalling your antivirus, the problem with Windows
Mail persists, delete that corrupted mail account, restart
Windows Mail, then recreate that account.
