Unable to send or receive mail

I can use my Hotmail account on the website, but when I go to my Windows Live Mail, I get this message:

Unable to send or receive messages for the Hotmail (kullmanvt) account.

Server Error: 4102
Server: 'https://mail.services.live.com/DeltaSync_v2.0.0/Sync.aspx'
Windows Live Mail Error ID: 0x8DE00001

I contacted Fairpoint, my internet provider, and they gave me some server settings to check, but I can't find where to do that.  We lost power overnight, and I wonder if that could have done something.

Thanks.
