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

Unfortunately, I can see both sides of this argument equally strongly.  When a reminder is created with an end date, then I, for one, would also have to remember to manually create a reminder for close to when that end date is, just to re-extend that end date when the time comes, for each recurring appointment.....what chaotic situation that sounds like!  Perhaps, when that setting was (silently) changed from "no end date," Microsoft also should have progromatically and automatically created such individual reminders of recurring appointments' end dates nearing.....that would have solved this problem, and could still!  True, it would be easier for us that need to, to try to remember to change the end date to none when creating a new recurring appointment, but even that is easier said than done (after decades of habit forming, creating recurring appointments in Outlook).

Is there no way to change the default back to "no end date?"  I just had another scary thought:  is it possible that the removal of "no end date" on June 25th applied retroactively to pre-existing recurring appointments??  How can I see what the end dates of recurring appointments currently are?  I ask that last question because, even if end dates were *not* retroactively modified, there may have been some recurring appointments I created *since* I was (just now) aware of this (June 25th) change....if so, I would need to go and adjust those back to "no end date," of course.

Lastly, for others in this thread who were asking if the "short default end date" could be modified, it looks like this article has the instructions to do that:  https://www.slipstick.com/outlook/calendar/encourage-users-to-set-end-date-on-recurring-appointments/

Unfortunately, that article won't help me, and my horribly bad (ADHD level/type bad) memory (as well as others like me). I had been relying on Outlook for decades for this purpose, and this change has definitely "pulled the rug out from me."  At the same time, if no end date recurring appointments truly clog Exchange servers with multiple, infinite appointments, I understand how that is not a good thing either, but I then wonder how those Exchange servers survived for the past few decades, with the default for recurring appointments being set to "no end date?"
