Warning! Hybrid deployment can cause duplicate mails in some environments. This is an issue with Hybrid deployment and not with your Barracuda Cloud Archiving Service. Contact your Barracuda Networks Sales or Support representative for more information.

To configure journaling via Script:

  1. Go to the Mail Sources > SMTP Journaling page.
  2. In the Journaling Setup Scripts > Office 365 Setup Script section, click Download to save the PowerShell script to your local system, or click Show Script to copy the script to your clipboard.
  3. Open Windows PowerShell, and run the script to configure Microsoft 365 to journal mail to the Barracuda Cloud Archiving Service.

If you are unable to run the journaling script and need to manually configure journaling, see Manually Configure Journaling.
