Hello. I have made no setting changes, but starting a few days ago, whenever I try to get email via Windows Live Mail (which has worked well for years), it returns immediately and says that I have no new email messages. No error message is displayed; by all appearances it is the normal response that would occur if there truly were no new messages.

However, I can access my account via hotmail.com, which shows that I have been receiving my usual number of messages. I can also send messages via hotmail.com, and they are received normally.

If I send an email message from Windows Live Mail, it is received by the addressee, but doesn't appear in my Sent Items there. Meanwhile, hotmail.com displays correctly all the email that I have been both receiving and sending.

What can be causing this?

--best regards
