Restore Requests for Emails Sent to Groups - End-User Experience

This procedure is applicable when these conditions are met:

  • Threat detection policy the email is matched on is in Protect (Inline) protection mode.
  • Email is sent to groups containing multiple users (not individual recipients or distribution lists).
  • Email is quarantined or its attachments are cleaned.

End-user experience to request to restore a quarantined/cleaned email:

  1. Click on the link in the email notification you received for the quarantined/cleaned email.
  2. On the User Verification page, enter your email address and click Submit.
  3. Avanan sends a verification code to your email address.
  4. Enter the verification code you received and click Submit.

Admin Quarantine Release Process

When the end-user requests to release an email, the administrator is notified via email to the configured Restore requests approver email address. The email contains a direct link to the email profile in the Avanan Portal. The administrator can do a full security review of the Malware from the Avanan Portal and can restore the email or decline the release request.

Restoring Quarantined Emails - End-User Experience

After the administrator approves an end-user request to restore an email from quarantine, Avanan performs these actions:

  • Removes the quarantine/clean email notifications received for the quarantined email from the end user mailbox.
  • Adds the original email to the end-user mailbox, where the email received time is the restore time of
    the email from quarantine, but not the original email sent time.

This example shows the initial email received by the end-user.

email-before-approval-by-admin

This example shows the same email received by the end-user after the administrator approved the restore request.

Note - The initial email received by the end-user is removed, and the restored email gets delivered as a new email to the end-user mailbox. The email received time is the restore time of the email by the administrator, but not the original email sent time.

Who Receives the Emails Restored from Quarantine

  • Emails quarantined by Avanan:
    • Depending on the configured workflow, Avanan delivers the email only to the requesting user or to all the original recipients.
      • If the user restores the email without administrator approval, Avanan delivers the email only to the requested user.
      • If the administrator releases the email from quarantine, Avanan delivers the email to all the original recipients of the email.
  • Emails quarantined in Microsoft:
    • Avanan delivers the restored emails to all the original recipients regardless of whether it is restored by the user or the administrator.

Notifying End Users about Rejected Restore Requests

To notify end users when their quarantine restore requests are rejected:

  1. Go to Security Settings > User Interaction > Restore Requests.
  2. In the User-Reported Phishing Emails section, select the Notify users when their reports are approved/declined checkbox.
  3. To configure the sender email address for notifications:

Dedicated Quarantine Mailbox / Folder

If you would like to store quarantined emails/files locally, you can configure a dedicated quarantine repository for every protected application. This repository is used to store every email / attachment / file that is  quarantined automatically according to the policy or manually by administrators.

Specifying such a mailbox/folder is not mandatory, as Avanan stores a copy of quarantined items in an S3 bucket associated with the Avanan portal.

Office 365 Mail

Note - The dedicated quarantine mailbox must be a full licensed mailbox and it cannot be a shared mailbox.

To configure the dedicated Office 365 Mail quarantine mailbox, go to Security Settings > SaaS Applications and click Configure for Office 365 Mail.
