How to trace bounced messages from Exchange Online
Question is how to access message flow for the messages that are bounced by Exchange Online server.
I have tried to trace messages that i sent to non existing email address on my Exchange Online tennat from outside like outlook.com. I cant find them in Exchange Online Old/New Admin Center.
Is there a workaround?
