Fix SharePoint Emails to Group Address Not Being Delivered
Question details
SharePoint successfully shares content with individual users but fails to deliver email notifications to company-wide group addresses.
- Product
- Microsoft SharePoint
- Device & OS
- not provided
- Scenario
- A user or administrator is attempting to send SharePoint alerts, content invitations, or notifications to a centralized group email address.
- Observed behavior
- Emails directed to the group address are not delivered, even though individual email notifications are functioning properly and the group address works when tested in Outlook.
Verify that the group email address is active, spelled correctly, and configured to receive external sender emails by testing a manual message delivery from Outlook.
Run a Message Trace and Open a Microsoft 365 Support Ticket
Since group delivery failures from SharePoint are often caused by backend routing issues, a tenant administrator must investigate delivery logs and escalate to Microsoft.
The fact that the group email works in Outlook does not rule out a SharePoint-specific backend issue. Microsoft 365 support requires detailed logs from your tenant to investigate why SharePoint services are failing to route messages to your group.
Log into the Exchange admin center, navigate to 'Mail flow', and select 'Message trace'. Run a trace for the affected group address over the past 48 hours to identify where the delivery drop occurs.
Log into the Microsoft 365 admin center as a Tenant Administrator. On the left navigation pane, click 'Support' and then select 'Help & support'.
Type a brief description of the issue in the search bar and press Enter. If the automated solutions do not resolve the issue, click 'Contact Support' at the bottom to open a new service request.
In the ticket description, include the affected SharePoint site URL, the exact group email address, the dates and times of the failures, and attach the Message Trace results.

Frequently Asked Questions
Why do SharePoint emails work for individuals but fail for groups?
This discrepancy can happen due to restricted group delivery settings in Exchange, backend synchronization delays between SharePoint and Microsoft 365 Groups, or anti-spam policies that treat automated SharePoint notifications differently when sent to a distribution list.
Can I fix SharePoint group email delivery without administrator access?
No. Troubleshooting this issue requires running a Message Trace in the Exchange admin center and potentially contacting Microsoft Support, both of which strictly require tenant administrator privileges.
What information does Microsoft need to resolve this SharePoint issue?
To expedite resolution, provide Microsoft Support with the URL of the affected SharePoint site, the exact group email address, the specific dates and times of the failed deliveries, any error codes received, and the exported Message Trace results.
