I have email sync but there are times when I send 1 email to 1 customer that I discuss multiple open deals. In the past, I would use the BCC address to make sure that email is copied to all the open deals. This morning I emailed a customer and BCC'd 3 deals that are open and I was discussing in the email. I noticed the email did not make it into  2 of 3 deals. When did this stop working?
