I have a blank line in the top of my blocked sender list.  Every time I try to remove the blank entry I get a message that Hotmail is not available. I can successfully remove any other entry in my blocked senders list.

I think this blank entry is responsible for an error I get whenever hotmail syncs with outlook.

Task *** Removed by moderator *** reported error (0x80004005) : 'There is an error synchronizing your mail account. Please verify your account is configured correctly by first accessing your mail on the web.  Error: 4202. '
