Outlook 2016 defaults to an end date on recurring appointments now - need "no end date" fix

Yes, server performance is absolutely not a reasonable explanation for making a change that is almost guaranteed to result in major inconveniences for many users--especially the most loyal ones. I personally have been using Outlook for over 2 decades now, and it has NEVER been this way. The whole point of the Outlook recurring events/appointments is to eliminate the need to juggle multiple future appointments/commitments in your head--it's supposed to be "set it and forget it". Having calendar events all of a sudden disappear from your calendar when you don't intend them to is completely counter to that premise. Even if this WERE a performance concern (which several people have mentioned, it's NOT), then the performance problem would be the appropriate thing to fix--not the functionality. The idea that it makes sense to hamper or remove critical, decades-old functionality users have come to depend on to improve performance is one I have a hard time understanding, at any level.
