Hi.

I want to share a few xlsx files with my collegues as part of a company Excel seminar. I want them to be able to select and edit anything once they open a file to allow them to learn from it, but I don't want them to be able to overwrite any files. How to do this? Sofar the best idea I saw was to merely set the files to read-only. I'm not even sure I would be able to do that, as the files will be on a server on which I'm no admin. No password is needed, I only want to prevent the files to be changed on the server. Office 2013, with possibly older ones in use at company. No sensitive material in the files.

Thanks:
Daniel
