Undeliverable reports email address

Hi mara2021

Thank you for posting to Microsoft Q&A regarding the undeliverable journal reports address in Exchange Online.

Based on your description, I understand you are in the process of decommissioning your on-premises GFI Archiver and want to ensure this transition does not result in delivery errors when disabling the existing journaling rule.

Please note that the configuration for the Undeliverable Journal Reports address (previously available in the Exchange Admin Center) is now managed through Exchange Online PowerShell. This address, defined by the JournalingReportNdrTo parameter, determines where Exchange sends notifications if a journal report cannot be delivered. For detailed information, please refer to this document: Configure Journaling in Exchange Online

Here are the steps to help you verify and update this setting:

# Connect to Exchange Online PowerShell  
Install-Module ExchangeOnlineManagement -Scope CurrentUser
Import-Module ExchangeOnlineManagement
Connect-ExchangeOnline -UserPrincipalName <******@yourdomain.com>   

# Check the current journaling rules 
Get-JournalRule | Format-Table Name,JournalEmailAddress,Enabled
 
# View the current undeliverable report address 
Get-TransportConfig | Select JournalingReportNdrTo   

# If the value is blank, configure a monitored mailbox or distribution list 
Set-TransportConfig -JournalingReportNdrTo "******@yourdomain.com"   

# Disable the existing journaling rule (do not delete immediately) 
Disable-JournalRule -Identity "GFI Journal Rule Name"

# Remove the Journaling Rule After Verification
Remove-JournalRule -Identity "GFI Journal Rule Name"

Once you have confirmed that journaling is no longer required and no undeliverable reports have been received (after monitoring the environment for several days), you may safely remove the journaling rule permanently.

Additionally, if the JournalingReportNdrTo value is not configured, undeliverable journal reports may not be delivered correctly: Transport and mailbox rules in Exchange Online or on-premises Exchange Server don't work as expected - Microsoft Support
