I used to use Hotmail and loved it.  However, I started having problems when I needed to use it for my work which included sending and receiving zip files.  Hotmail apparently had some limit/block and the zip files would never make it through to my email.  So I switched to Gmail and have never had any problems with receiving or sending zip files.  I'm not a big fan of the Gmail format but love the clean look of the new Outlook.com.  Has anyone had any problems with zip files or do you know where I can find out what the limits of size are for outlook.com ??
