Installation:
Install the cab file located here to your windows mobile device.
After installation launch the program rk-OSR from the programs and go thru each tab page to configure it and finally save the settings (make sure the Enable check box is checked) test the functionality if working properly. Then close the application. Now the sync should happen at next specified schedule.

One touch synchronization
A Very good feature for people checking mail manually, so that you do not have to switch accounts and click the sync menu each time or start/stop wifi etc, just one click to do that now. You can also assign this shortcut to hardware buttons. The new install adds a new program icon called 'rk-OSR-Now' to your programs list. But you need to do the following procedure done before attempting 'rk-OSR-Now' shortcut:
- You should configure the 'rk-OSR', and make sure it is working properly and you are able to synchronize your accounts properly.
- You must edit the shortcut, rk-OSR-Now; add additional text "Now" without quotes. Basically your target should read as below "\Program Files\rk-OSR\rk-OSR.exe" Now
