Outlook is slow in Hotmail

When I am trying to do a send and receive in Hotmail inbox, Outlook sync the entire box and will take 20 minutes or so before it’s over. Then when syncing again the next time, the process will not work again. When moving in to Hotmail inbox, it will take 30-60 seconds and a message will appear stating: synchronizing message headers. My Outlook is acting real slowly with my Hotmail accounts but its okay with any POP3. Can someone help?
