Our company needs to collaborate on a Excel sheet that will be accessed by coordinators located in Scandinavia and the US. If the file is already is opened by one coordinator, is there a way that the next one trying to open it can get access something like: "view only, file is in use", or can the file be opened by two at the same time and the "winner" is the one who saves last?

In our corporate net we do get this kind of file locking, but is it possible on DriveHQ

Thanks
John
