About a month ago, Outlook Express (6.0) stopped working (as configured with Hotmail.)

I can send messages (out of O.E. via the Hotmail account)...I can then go to my Hotmail account on the web; & the messages are in the "Sent Items" folder (just as they are in the Hotmail "Sent Items" folder in Outlook Express)...but no one ever gets the messages.

If I send messages directly from Hotmail on the web, they go out fine.

Same deal with incoming.

What gives?
