So heres the deal blackberry using the redirector software, its sending and recieving just fine, except to one person. That one person hes been able to send to before, but now when he tries to send from the blackberry it goes through and shows a blue check mark....and about 10-15 seconds later shows a red x, and the person never gets the email, and if he sends it from outlook then it works just fine.
Outlook is also operating off of exchange.
I've regenerated keys manually, and ive also reactivated. Is this between the blackberry and the computer? He is just pressing reply and not changing the email address at all, I did it myself as well.
