In Outlook 2007 we send a mass email to our members using the BCC line and adding the group. We leave the To: line and the CC: line blank insert our message and the first one goes out fine with no kick backs. The problem is if we send 2 or more out a day we get a system email back stating Your message did not reach some or all of the intended recipients. So it works for one per day. Please help
Your message did not reach some or all of the intended recipients.
