Hi Sophie, 

Welcome to Box Community and glad to help!

Let me create a new case and a member of our team will be in touch, please keep an eye out.

Thanks for posting!

Same issue here. Plus, when I save or save-as, the file name corrupts, adding in lots of characters like this:

For instance, "Quarterly Conversation Form" becomes "%20Quarterly%20Conversation%20Form" when I try to save. And defaults to local drive rather than Box.

I also am having this issue as of a few months ago. Every time I "save as" a file on box drive, Windows defaults to "Documents" instead of the originating folder. It's infuriating and costing me a lot of time. Please let me know how I can fix this ASAP.

Box Support tried to help but concluded with "it's a Microsoft issue not a Box issue." The workaround I have discovered is instead of using the F12 "Save As" shortcut I go File>Save a Copy which defaults to the originating folder

That's clever, Sophie! I'm now doing what you suggest in Excel. With Word, still no luck, even with my default save location being a Box location.
