Migrating Outbound Protection to Exchange Online (Inline Mode)

  1. Log on to the Cloud App Security management console.
  2. Go to Administration > Service Account.
  3. Locate your Exchange Online (Inline Mode) service account and click Migrate Outbound Protection.
  4. Click Disable after Step 1 to disable the existing outbound protection that uses the Exchange mail flow service account.

    This step prevents new emails from being quarantined.

  5. Click Click here after Step 2 to go to the Quarantine screen and restore emails quarantined by the existing outbound protection if necessary.
    Important:

    After the migration, the quarantined emails will be removed and can no longer be restored.

  6. Click Migrate after Step 3 to migrate outbound protection to the Exchange Online (Inline Mode) service account.
    During the migration, Cloud App Security performs the following:

    • Deprovision the Exchange mail flow service account for outbound protection.

    • Upgrade the Exchange Online (Inline Mode) service account to support outbound protection by adding the following:

      • Transport rules, connectors, and a Microsoft 365 group in your Exchange Online service

      • Default Advanced Threat Protection and Data Loss Prevention policies for outbound protection

  7. Wait until the process is completed.
  8. Hover over the Tasks icon in the upper-right corner of the management console.

    If the messages "Enabled outbound protection for Exchange Online (Inline Mode)" appears on the Tasks screen, the migration is successful.
