  • You can use transport rules as describes below article,

    https://docs.microsoft.com/en-us/exchange/security-and-compliance/mail-flow-rules/inspect-message-attachments

    It's possible after you creating. But don't know the possibility for mails, before creating rule.

  • There is no way to do a search with such criteria, best you can do is get a list of messages with specific attachment types. Then you will have to check each of them whether any of the attached files are password protected.
