A Microsoft file hosting and synchronization service.
I have this issue and it is massively fustrating, there is no reason why MS should insist on where we save our personal or work files, I am on a mac and none of these options exist !! Every time I have to open or save (new document) I have to go through added steps to select my local drive ........................................... WHY ? there is no efficiency to be gained here other than driving me to one drive which I have but do not use to save documents.
I have attempted so many solutions, none of which work, nothing in preferences (settings) nothing in the save dialogue... Im an advanced user and this is impossible to change.
