Malware Detections Report
I have been looking at the Malware Detections report for our tenant. I have noticed a lot of malware detections showing as outbound and the sender and recipient address is spo_arbitration_GUID@MyDoma...
I have noticed that we have messages flagged as outbound malware on the Malware Detections Report as well. When I dig deeper, the sender is xxxx@notmydomain.com, and there are always two rows with two different recipient addresses (but the same user) listed: yyyy@mydomain.onmicrosoft.com and yyyy@mydomain.com
Any idea why this may be?
