We have an SBS-2003 Sp2, running exchange V6.5 (build 7638.2 SP2), and I created a self-signed certificate to replace an expired exchange certificate and OWA from PC's works no problem. the problem is, none of the mobiles devices connect even for the android Firefox browser. tried to run ICW to modify security settings but the program doesn't run, starts but stop after a few seconds.
I thought I might install PowerShell v2 for SBS2003 but there is no support for exchange!
I need help to fix this problem!
