Fired up OneNote a day or so ago and it failed to start, I tried to start it again and was greeted with the following error – “OneNote Error – We Couldnt Start OneNote the last time we tried“.
My Laptop had just ran it standard update schedule so I checked if anything had been installed, sure enough there was a new update – KB4462238. It seems this is a known issue and the update has since been removed from distribution, but you, like me may have already updated OneNote.
Microsoft have released a statement and the standard update removal procedures resolved this issue. Take alook at the link here.
