I like the idea in Exchange Admin to be able to block or notify senders/recipients/people about emails with "Sensitive Information", such as driver's license ID's, Social insurance numbers, banking info, etc. This is done with Mail Flow rules.

There is a large amount of "Spam" or "attacks" on email accounts where a scammer is requesting BitCoin or they will release videos of the person or do something else to harm them.

I would like Microsoft to add BitCoin Wallet (as a start and then other Cryptocurrency ID) to the "Sensitive Information" list. So I can then either block or quarantine those emails.
