That probably won't work either.
You probably have one of the newer "11 speed" rear derailleurs that require much more cable pull than older ones. That 10 speed Microshift is going to have the exact same shape as your current shifter, and the exact same problem. For those shifters you need to stick with derailleurs based on Shimano road 6-10 or mtb 6-9 speed.
This is why I asked if you changed derailleurs.
