This is a sponsored Microsoft community, and you'd think they would monitor it for feedback. This issue has been around in one form or another for a couple of years with no acknowledgement or solution. So, it's not clear if MS pays any attention to their own forums or really cares about customer feedback despite all their PR to the contrary. I have dug pretty deeply over the years to find a way to get through to them but in most cases I have not been successful.
In each of the desktop Office programs there is a Feedback button on the Help menu. There is also a Contact Support button on the same menu. I've used both and have received replies, but not much in the way of real in-depth help. Most of what comes back is pretty standard ... run a diagnostic, reboot, reinstall. Nothing very insightful.
I wish I could be more positive, but this seems to be the current state of play on this issue. There are quite a few people experiencing this problem but not enough to get Microsoft's attention.
