Just want to add my experience to the others.  Since installing the upgrade Live Mail does not receive mail from Outlook.com, with or without attachments.  But I can send mail.  Live Mail reports no error message and appears to operate normally, but downloads nothing.  I've downloaded and installed the latest update but that did not help.  I also tried deleting my hotmail.com account and recreated it but that also did not help.  My Verizon account is accessed by Live Mail to but it continues to work normally and has never been affected by any of these problems.  

This is a serious problem for users because emails cannot be saved to the PC, something I do many times per day.  Please get this resolved soon.
