Better Diagnostics and solutions
I try to make any file online-only and get the message "unspecified error". This says nothing and gives no clues for what to do to solve the problem. Add better error messages and also a button to click on which leads to a web page that describes how to recover from the error. Right now I have sent logs to Microsoft twice (8 weeks ago !) and get no response which probably means that the information is not enough and better information is needed to resolve problems.
