i am having a similar problem. I recently bought my laptop, and I installed outlook, and I also redirected all my emails from Yahoo! to hotmail, now when I go in to set the account up, so I can get my emails on outlook, it works fine but everytime I try to either send and/or receive emails, it keeps giving me an error as shown below Task 'Hotmail: Folder:Inbox Synchronizing headers.' reported error (0x800CCCF6) : 'An unknown error has occurred. Please save any existing work and restart the program.' Task 'Hotmail: Folder:Outbox Synchronizing headers.' reported error (0x800CCCF6) : 'An unknown error has occurred. Please save any existing work and restart the program.' Task 'Hotmail: Folder:Sent Items Downloading all items.' reported error (0x800CCCF6) : 'An unknown error has occurred. Please save any existing work and restart the program.' Can somebody help me??? url:http://www.ureader.com/msg/10761668.aspx
