Frequently Asked Questions
Where can I find audit logs for cloud-only distribution list changes?
Search the Microsoft 365 audit log in the Microsoft 365 Defender portal for Azure AD group administration activities, or open Azure Active Directory > Groups > Audit logs in the Azure portal.
How long do distribution list audit log entries take to appear?
Allow up to 24 hours for entries to appear. If the event is still missing, confirm that auditing is enabled, your account has permission, and the selected date range includes the change.
Why aren't distribution list changes showing in the Exchange admin center?
Cloud-only distribution lists and Microsoft 365 groups may not generate the same Exchange admin center audit entries as mail-enabled objects. Use Microsoft 365 or Azure AD audit logs instead.
What Microsoft 365 audit log activities should I search for?
Use Azure AD group administration activities such as Add member, Remove member, Update group, and Delete group, and filter by the affected group or user.
