ActiveSync repeated responses

Exchange ActiveSync occasionally gets stuck in a loop and repeatedly replies to meeting invitations. This has apparently being happening for decades. No idea how we avoided it until recently.

This is happening on iOS versions as late as 17.2.1. It seems (SEEMS) to manifest when users reply from their iOS device. Mail server logs show different message IDs for each reply, so it's not the server repeatedly sending a reply, but the device repeatedly generating and sending the reply.

I manage 100 users and this is a serious problem with regard to our clients.

I see many threads and posts about this that seem to just fizzle after a while. Does anyone has a definitive solution to this problem aside from users switching their calendars off/on and repopulating from scratch? That's hardly a viable solution in a workplace (also, the user usually has no idea there's a problem .... only the recipient knows because they're the ones getting slammed will multiple replies).
