After 7 months of near flawless performance, my exchange services (corporate email) is no longer working and giving an error "Exchange Services has Stopped". I have done soft resets, powered down and on, deleted the email account and added (which I can no longer do as a result of Exchange Services stopped) with no improvement. I am not rooted BTW. Has anyone else had this happen, and found a solution? I hesitate to do a factory reset because I do not want to start over reinstalling apps and data and personalizing my stock launcher home and other screens. And, not sure a factory reset is the solution. Is there a way to save or back up your customized launcher screens so that you do not have to rebuild them after a hard/factory reset? Thanks for your help.
