I had noticed awhile back that when I go to enter a group list in the BCC section, the email sends, but not to any of the multiple names in the group folder, no error message is received. if I would type out 20 individual addresses, it would send.

This happened on my previous computer, got a new computer, and same problem on new computer. I have to flip to Outlook to send mass email.

Does anyone know why this is, or how to solve it?
