I am facing an issue with Group Mail moderation in our hybrid environment. We are using Exchange Server 2019 on-premises with some moderators hosted in Microsoft 365.

The problem is as follows:

  • Emails sent to the group are not being routed to Microsoft 365 moderators for approval.
  • The group has been configured with multiple moderators, including two users whose mailboxes are hosted in Microsoft 365.
  • However, the moderation notification emails are successfully delivered to on-premises moderators only.

We have already checked the following configurations:

  1. Moderation settings in the group properties are correct.
  2. mail flow and connectors are functioning properly for other email types.
  3. No transport rules are blocking these notifications.

It seems there might be an issue with moderation emails specifically for Microsoft 365 users.

Could you please assist us in resolving this issue? Let me know if you require further details or diagnostic logs.

Environment Details:

  • On-premises Exchange Version: Exchange Server 2019
  • Affected Users: Microsoft 365 moderatorsI am facing an issue with Group Mail moderation in our hybrid environment. We are using Exchange Server 2019 on-premises with some moderators hosted in Microsoft 365. The problem is as follows:

    Hi @Mohammad Samiul Islam ,

    Welcome to the Microsoft Q&A platform!

    Based on your description, you are experiencing issues with group mail moderation in a hybrid environment. Here are a few steps you can take to troubleshoot and potentially resolve the issue:

    1. Make sure the Hybrid Configuration Wizard (HCW) has run and completed successfully. This is critical for proper mail flow between the on-premises and Microsoft 365 environments.
    2. Audit emails are processed through arbitration mailboxes. Verify that these mailboxes are healthy and configured correctly. You can check their status using the Get-Mailbox -Arbitration command.
    3. Even though you mentioned that the transport rule is not blocking the notification, it is worth revisiting the connector. Make sure the connector is configured correctly to route the audit email to Microsoft 365.
    4. Use the message tracking log to track the path of the audit email. This can help determine where the email is stuck. You can use the Get-MessageTrackingLog command for this purpose.
    5. Make sure the permissions required for cross-forest auditing are set correctly. This includes verifying that the Microsoft 365 auditor has the necessary permissions to approve or reject the message.

    Please feel free to contact me for any updates. And if this helps, don't forget to mark it as an answer.

    Best,

    Jake Zhang
