I have two Samsung phones connect to my Exchange email using ActiveSync.
When I manually add a contact they are stored on the phone and not ActiveSync, how can I set the default storage mechanism to be ActiveSync?
Please make sure contact syncing is enabled for the particular activesync account. You can check by going to Settings > Accounts. Select your activesync account and ensure Contacts are selected. You can also check accounts settings from the contact app by opening the menu. Then try creating a new contact, it should prompt you to choose a destination (phone, email etc).
