This guide describes how users and administrators of Mimecast for Outlook v7.7 or later see and interact with banners displayed inside messages if:
- Their Mimecast account has Targeted Threat Protection: Impersonation Protect enabled.
- A message has been flagged as suspicious or contains an inbound item from an external source.
Identifying Suspicious Messages
To report the message as a phishing attempt:
- Click on the Report Phishing button.
Forwarding Suspicious Messages
By default, an alert notification is displayed if a user attempts to forward or reply to a message where an Impersonation Protection policy is triggered that uses a definition with the "Tag Header" option enabled. Administrators can enable or disable users ability to forward or reply to suspicious message.
To enable forwarding and replying to suspicious messages:
- Select the Impersonation Protection in Mimecast for Outlook - Forward and Reply to Suspicious Messages option in the "Common Application Settings | General" section of your application settings. See the Configuring Application Settings page for full details.
Identifying External Messages
An external message banner is displayed if an Impersonation Protection policy is triggered, that uses a definition with the "Mark All Inbound Items as External" option enabled with the "Tag Header" option configured.
