I am using Microsoft document connection on daily basis, before a week it fails. I am unable to use that. I cannot see my files and canít sign in. This problem occurs when I am trying to open a file. It is very frustrating because in my word file it contents some important data files and I need to use on regular basis. I donít know why is this happening if anybody having same experience then please give me some idea to solve this problem. If there is any additional software required to solve this issue then please let me know.
