I have a Nokia XM5800. I have installed Mail For Exchange in order to synchronise my email, contacts, and calendar with my phone. Everything I do to try and sync results in the error 'System Error. Try Again Later'
I have gone through all the settings carefully to ensure that I have got everything as per the instructions. I have also tried just syncing one item i.e. just contacts, just calendar, just email. These do not work and display the same error.
Finally I created a new gmail account and swapped in the new email, password etc. This DOES work. So it appears to be something specific to my gmail account? I am however successfully synchronising my ipad using activesync protocol.
