Insane response from Microsoft support

Long story short; we have a widespread issue with Outlook users regularly being unable to send replies from Microsoft 365 Group mailboxes. When the issue occurs, they'll click reply, write their response, and click send, then their draft will vanish into thin air and they'll get an error stating, "This message can't be sent because it no longer exists. It can only be discarded."

We spent about a month working with Microsoft support on this, providing them with repeated screenshots, recordings, network traces, etc, then eventually they came back saying the internal product team had applied a "global fix", and asked us to confirm if the situation had improved.

Some users I spoke to said that yes, the problem appeared to have cleared up for them, but others complained that they had seen no change and were still encountering the same issues with the same frequency, so we reported that to Microsoft support.

Off they went to investigate again, but before long they were back with another update...

The issue we are experiencing is... wait for it... BY DESIGN.

Yes, you read that right. Microsoft claims that it's "by design" to be randomly unable to reply to emails from a Group mailbox!

I mean, putting aside how laughable it is to suggest that data loss and emails failing to send is intentional, if this were truly by design, then it would happen all the time; not just randomly 30-50% of the time, because why on earth would you design something to fail intermittently?!

Anyway, they finished off by saying they would be closing the case, but also that it was on their roadmap to make improvements in this area, so I asked if they could at least link me to a roadmap item where I could monitor their progress, and they sent me this: https://www.microsoft.com/en-us/microsoft-365/roadmap?searchterms=group+issue

Fantastic! Thanks for nothing!

At this point, I just give up.
