I already thought I had once and for all set the language to Swedish in Office 365. But now I try to create a new OneNote for Classroom. And the program insists on that I want spell checking and I want it for English. I deselect spell checking. Still the program converts i to I! You have no idea how much that off non English writers! I have an account on O365. I have settings I try to put right. What causes my settings to get screwed up all the time? The browser I happen to use? The Windows I happen to use? The organization that I'm working at and their centrally chosen settings? All those causes are utterly wrong! Get that! Only thing that matters is what I want and what I try to set in my personal settings in O365!
