Hello DKS_207,
Thank you for your question regarding the use of email-enabled security groups when creating rules on a modern SharePoint Online list or library.
Currently, SharePoint Online’s built-in rules feature (such as “send an email when an item is created”) is primarily designed for individual users and does not reliably support sending notifications to email-enabled security groups. While these groups can be used for permissions and access control, they are not consistently recognized as valid recipients for rule-based notifications.
Key Considerations:
- Rules vs. Alerts: Traditional alerts (now being phased out) had similar limitations. Rules are more restrictive and typically require individual user accounts.
- Permissions: You can still use mail-enabled security groups to manage access to lists and libraries.
- Workaround: For broader notification needs, we recommend using Power Automate to create custom flows that can send emails to distribution lists or groups.
