I have Windows Live Mail 2012, Version 2012 (Build 16.4.3508.0205) installed on my computer. I also use Windows 7 operating system. I have set up a new category folder under contacts and have placed 48 addresses in this category folder. When I want to send mail to the 48 addresses, I put the group mail category in the Bcc:  field and my own address in the To: field.

When I try to send the message, the 48 addresses do not send. Is there a limit on how many addresses you can put in a category? I tried a new category with just a few addresses and it works.
