Re: Security in Windows Mail

First, test your password by logging in to your provider's webmail: or
If that works, it proves you have the correct username and password.
A likely reason for the username/password failing in Windows Mail is
account corruption. One thing you should try as a possible quick fix is
to delete that corrupted mail account, restart Windows Mail, then
recreate that account.

If that doesn't fix it, more drastic measures will have to be taken.

although that may not be sufficient to eliminate all bad effects.
In a worst case scenario, your antivirus may need to be uninstalled.

If turning off the email scanning function does not resolve your problem,
consider upgrading to Windows Live Mail, because it is less prone to
suffering bad effects from overly aggressive antivirus programs.

Email scanning in any antivirus must be disabled, for reasons
