Deprecation of Mail flow features in classic Exchange admin center in WW service

KevinShaughnessy  Any update on this? Same as others, I can only search against a suggested search result. Fortunately, these searches do at least return results for messages sent to any of that mailboxes' aliases. (non-primary addresses, Plus Addressing, etc)

Not being able to pare that down prior to beginning a trace is quite frustrating, especially since the results don't show the original To: before address resolution/matching.

Example: I have a primary of sample @ mycorp.com I send a message to sample+test @ mycorp.com. I trace for messages sent to the mailbox (same suggested result being discussed here). I see the message trace for this message, but only see the recipient as sample @ mycorp.com. I wager I'd have to run an entire extended report to get a chance to see that.
