Configuring Misdirected Email Prevention

The Outlook Add-In performs real-time checks during user actions such as Send, Reply, Reply All, and Forward. When a potential risk is detected, the system displays an on-screen warning to the user before the email is sent.

To view the supported devices for the Outlook Add-In, see Outlook Add-In - Supported Outlook Types and Platform.

Misdirected Email Prevention requires a DLP license (either the DLP add-on or the Complete Package).

To configure misdirected email notifications:

  1. Access the Avanan Administrator Portal.
  2. From the left navigation panel, go to User Interaction > Misdirected Emails.
  3. Enable the required categories toggle buttons and click Save Changes. See Misdirected Emails Categories.

Responding to Misdirected Email Warnings in Outlook - End-User Experience

If an administrator has configured the misdirected email notifications in the Outlook Add-In, it performs real-time checks during actions such as Send, Reply, Reply All, and Forward.

When a potential risk is detected, an on-screen warning banner appears in Outlook before any action, allowing a user to review the details.

For more information about the permissions requested during Outlook Add-In sign-in, see Outlook Add-In Permissions.

To respond to a misdirected email:

When the warning banner appears, review the email details shown in the alert.

  • If the information entered is correct, select Send Anyway to proceed.

  • If the suggested correction is correct, select Replace & Send to apply the change and send the email.

This ensures emails are sent to the intended recipients while reducing the risk of accidental data exposure.

Outlook Add-In Processing Message During Email Send

In some cases, when the user clicks Send, Outlook may display the following message:

One or more add-ins couldn't complete processing your email.

This issue occurs when the user performs another action that moves them away from the message being sent before the Outlook Add-In finishes processing the email.

Examples include:

  • Clicking another email

  • Switching to a different Outlook folder

  • Navigating away from the compose window

  • Changing focus before the add-in completes its processing

When this occurs, Outlook interrupts the send process and prompts the user to select an action, such as Wait or Save as Draft.

Recommended User Action:

The user should click Wait and allow the Avanan Outlook Add-In to complete processing the email before continuing to work in Outlook.
