When opening excel (not only a file but just the program in the PC) it gives me always the same error: "Sorry we could not find https://.... sharepoint.com..." I do not even understand what it means I do not understand why it appears but it reminds to a colleague of mine. I am wandering if it comes form copy and paste or similar. It has been going for more than a year. Two of these alarm windows appear every time, one when I click (no opening just one click) and the second when I try to open the file. Then, two excel windows appear, a useless one and the one I need.
