I recently had to do a factory reset of my Lenovo laptop and have now gotten almost everything back as before, except for the fairly frequent sync issues being generated for some unknown reason. I deleted several of the default folders that I have never used; could that be the problem? One of them was named "Sent Mail". There has never been anything in it when I looked; my sent mail goes to folder "Sent".

Any help will be greatly appreciated!
