Hi All, I am a newbie to the Andriod World. Got a HTC Explorer 6 months back There i set up my corporate email account, which worked really good without any issue. Last week it failed to sync even after repeated attempts. Then I thought of removing the account and set up again. Once deleted i am not able to set up the Microsoft Exchange ActiveSync account. I have even resetted the mobile to factory settings also. But still not able resolve the issue. It always throws an error.."Authentication Failed..... Can any one guide me to resolve this.
