Retrospective Verdict Email not Found in Tracking

[myerss]

Hello,

Occasionally we will get the Retrospective verdict received emails from our IronPort C300V. However, sometimes when we copy and paste the SHA256 hash in to the message tracking to have a closer look at the message, it comes back as not found. Is there a reason for this? Has the message been completely erased from the system?

Thank you!

Shawn

Let me have a look the next time I get one.

My understanding is that it should at least still be recorded in message tracking but removed from the O365 tenant.

Regards

Marc
