After activating Office 365 Mail or Gmail, Harmony Email & Collaboration performs several calibration processes for the Anti-Phishing engine.

The processes include:

• Scanning 13 months of email metadata (sender, recipient, subject, time) in users’ mailboxes to determine the communication patterns.

• Automatic identification of MTAs placed before Microsoft or Google. It could affect SPF checks and other aspects of detection.

While these processes are running, Harmony Email & Collaboration will be in Learning Mode. You can see a banner at the top of the dashboard. Also you can see the progress of the Learning Mode in Overview tab.
