Problem with Blackberry BIS into Exchange OWA corporate email accounts.
I have 12 Blackberry Curve 8330 using BIS with OWA into corporate 2003 Exchange Server SP2. None of them can reply or forward messages to internal domain accounts or external yahoo accounts. I can send new messages and receive messages. I dont have BES or Blackberry Professional Software. Nothing wrong with OWA, I can connect from anywhere with a PC. Windows based smartphones are working fine, iPhones are working fine with EAS. I have one BB with AT&T and that is the only one working fine, the rest are Verizon &Any thoughts?
