You can achieve multiple objectives with this report.
You will see the list of suspected emails, who they were from, who they were sent to and why they have been quarantined.
If you click on the Subject line for the email you want to investigate, this will open a representation of that email in a safe sandbox form to protect you from anything in that email that might be suspicious. After looking at the email, you can determine if in fact this is a legitimate email or is in fact Spam or possibly malware.
If you click on the Magnifying glass at the right, it will show you all of the details for the email as well as any attachments or links in the email. Be very careful about clicking on any of the links as this will remove you from the safe sandbox environment and take you directly to that link.

Once you determine if this is a valid email or not, after selecting the email, either by clicking on the magnifying glass to the right, or placing a checkbox at the left for that email, you can click on the Release Options dropdown if you want to release this email or the Deny Options dropdown if you want to deny this email.

When you are done, you can click the Red close icon in the top right hand corner.
