Excel: přímá kooperace s dalšími lidmi

Jakou máš verzi MS Office?
Taky řekneš v servisu "Nejede mě auto"? Jak se ta nefunkčnost projevuje?
A hlavně - jseš si jistý, že opravdu splňuješ tuto podmínku?

Only individuals with an Office 365 subscription can to take advantage of Excel’s new functionality and collaborate in real time.

A opravdu postupuješ dle návodu z výše odkazovaného článku?

Before you can use Excel’s sharing options, Microsoft requires that you use one of their file-storage options: OneDrive for Business, SharePoint Online or OneDrive.
* You must also be logged into an active instance of Office 365 to take advantage of the collaborative tools.
* Turning on the auto-save function is the next critical step to ensure that your changes aren’t overwritten by others.
* Sharing workbooks is relatively easy:
-- You access the tools through the in-app “Share” button located on the upper right-hand side of the screen.
-- Add your collaborators by typing them in, or looking them up via your linked Outlook address book.
-- An added bonus is the ability to select the type of collaboration rights you want for specific individuals. This ensures the sanctity of your spreadsheet.
-- One caveat to keep in mind: You can either make the spreadsheet “read only” or “full editing”— There really aren’t any in-between options available.
