If you use the Outlook Hotmail Connector, you may have already been prompted to update to the new version:

Outlook Hotmail Connector

This version 14.2 update corrects a number of sync issues, improves performance, and turns off the junk mail filter in Outlook in favor or Hotmail's own filtering system. If you've made entries in Outlook email filters (e.g., Safe and Blocked Senders), don't worry: These will still work and synchronize with Hotmail.

If you use Outlook and Hotmail and don't have them integrated, you can download Outlook Hotmail Connector 14.2 for Outlook 2003, 2007 and 2010 32-bit or Outlook Hotmail Connector 14.2 for Outlook 2010 64-bit.
