We have a client running Exchange 2003 SP2, and a few users would like to sync their Android phones - a Motorola Droid and an LG Ally, both running Android 2.1. Both phones give us the following error when configure a sync account: This Exchange ActiveSync server requires security features your phone does not support. I've made sure that Exchange ActiveSync is working, I've tried allowing unsupported devices in Exchange System Manager, adding the users to the device security exclusion list, but I'm not coming up with anything that will allow the Android devices to sync. What am I missing? What other information can I provide that would help find a resolution? Thank you for your advice!
