I have added my work exchange email account to my Samsung Galaxy S. It starts to downloads email, contacts and calender entries but then starts to freeze or pop-up screens appears saying that there is no contact with TwLauncher - it doesn't matter if I choose "wait" or "force close". Even if I delete the exchange account the phone keeps freezing and I have to do a phone reset (with all the setting up and downloading of apps to follow). I have tried to set up the account on a clean phone with NO other apps installed - same problem. What do I do? Our server is Exchange 2003. It works fine with my colleagues Nokia and HTC phones.
