My WLM was working fine for a year and all of the sudden I started getting a 5102 sync error and now I am getting this one... It will not recieve my MSN mail or send ANY mail. Also if I log onto hotmail via explorer it says my password is wrong but I can access hotmail with safari??? I am on a PC.

The message could not be sent. The authentication setting might not be correct for your outgoing e-mail [SMTP] server. For help solving this problem, go to Help, search for "Troubleshoot Windows Live Mail", and read the "I'm having problems sending e-mail" section. If you need help determining the proper server settings, please contact your e-mail service provider.
The rejected e-mail address was 'xxxx@xxxx.com'.
