I am helping a friend. He is running Windows Live Mail with Win7. He is trying to paste a list of e-mail address from Excel file into the bcc address field. I am familiar with how to do it in Outlook, which is not working with Windows Live Mail. The first error message is that commas or semi-colons are missing (Outlook adds them automatically). He added the semi-colons manually to the Excel spread sheet (what a pain). Now he gets an error message that some of the the addresses are not valid so the message cannot be sent. (Note: I pasted the same list directly into Outlook and it worked just fine.)
So what are the tricks in using Windows Live Mail?
