A sobering thought this – your Office 365 mailbox may be harbouring emails containing spear phishing and targeted attacks.
The free web-based Threat Scanner for Office 365 from Barracuda uses their Sentinel Artificial Intelligence engine to scan for threats already in your Office 365 account. It identifies advanced threats and includes information such as the sender of the risk, and details about the risk including what the risk is targeting.
As Barracuda describes here https://campus.barracuda.com/product/sentinel/doc/78807326/barracuda-email-threat-scanner-for-office-365/ – the free Barracuda Threat Scanner for Office 365 scans for
- Spear phishing attacks

Scan results are generated and a report sent to your registered email address within 24 hours.
