Microsoft has been very clear that they are not currently interested in console VR, and there are a few key reasons why.
Firstly, Microsoft has stated that they don't believe that VR is ready for the console market. They believe that VR is still in its early developmental stages, and that it needs more time to mature before it can be successfully introduced into the console market.
Secondly, Microsoft is also very aware of the high cost of VR hardware. They believe that the current VR hardware is too expensive for the average console gamer, and that the price needs to come down significantly before they would even consider bringing VR to the console market.
Lastly, Microsoft has said that they don't want to fragment the console market by introducing a new platform that not all gamers would be able to enjoy. They believe that it's important for the console market to remain unified, and they don't want to do anything that would jeopardize that.
So those are the key reasons why Microsoft is not interested in console VR at the moment. They believe that VR is still in its early stages, that the current hardware is too expensive, and that it would fragment the console market.
