As the email get rejected at edge level, does it possible to know from which sending IP emails got rejected in Defender for o365 portal ?

- Depends on which filter blocked it, but generally speaking no. Run a message trace based on sender/recipient details, if it's not visible therein, it's either blocked on the edge or never reached M365.
