Based on the scenario provided, the IT administrator of the company with a Microsoft 365 subscription and Microsoft Defender Plan 1 licenses received a report of an email that was put in quarantine suspected of containing malware while they were on summer holiday. When they returned to the office, they opened the quarantine page to investigate the message but found that it was missing.
The reason for the missing message could be one of the following:
A. Messages containing malware are automatically released to the user's email junk box after 10 days. This option is not likely to be the reason because the message was put in quarantine, not in the user's email inbox. Additionally, even if it was in the user's email inbox, the option states that messages containing malware are released to the junk box, not deleted.
B. You must upgrade to Defender Plan 2 to view the message. This option is also not likely to be the reason because the IT administrator has Microsoft Defender Plan 1 licenses. The Defender Plan 2 is not required to view messages in quarantine.
C. Messages that contain malware are retained for 15 days before being deleted. This option is a plausible reason for the missing message. Microsoft 365 automatically quarantines messages that are suspected of containing malware, and they are retained for 15 days before being deleted. It is possible that the 20-day delay in the IT administrator's investigation caused the message to be deleted from quarantine.
D. Messages that contain malware are deleted immediately. This option is not likely to be the reason because Microsoft 365 retains messages in quarantine for 15 days before deleting them.
In conclusion, based on the scenario provided, the most likely reason for the missing message is that it was automatically deleted from quarantine after 15 days because it contained suspected malware.
