I know they’re not explicitly selling SkyDrive or OneDrive or whatever it’s called now, but they kinda are.
What’s funny is, this file is stored in an encrypted container that does live in the cloud. 😄
Edit: Thanks to user @NoneYa@lemm.ee I now know about F12 in Office applications to bring up the “classic” Save As… dialog. Today I learned!
It still does, provided you use the “Save as” keyboard shortcut (F12). No such way, however, to prevent Outlook’s OneDrive shilling whenever you attach an Office file.
