It doesn't block Microsoft trackers due to a search deal:

> For non-search tracker blocking (eg in our browser), we block most third-party trackers. Unfortunately our Microsoft search syndication agreement prevents us from doing more to Microsoft-owned properties. However, we have been continually pushing and expect to be doing more soon. > > We've been working tirelessly behind the scenes to change these requirements, though our syndication agreement also has a confidentially provision that prevents disclosing details. Again, we expect to have an update soon that will include more third-party Microsoft protection.
