Question

How do we find who send Guest user invitation to an external user?

Answer 1

@a-Jayaprakash Ganesa Thank you for reaching out to us, As I understand you are looking for details who send Guest user invitation to an external user? You can review the Entra ID Audit logs, look for activity type - "Invite external user" which provides more details on the invitation sent to the external user, who initiated it.

Also, there is a sponsor's attribute (in preview) in the user attributes section which tells who invited the guest account to Entra ID. Below is the screenshot from my lab, how sponsors attribute can be viewed (in the below screenshot MOD Administrator is the display name of the account who initiated this invite)

Also, same can be viewed from Graph explorer too - https://learn.microsoft.com/en-us/graph/api/user-list-sponsors?view=graph-rest-beta&tabs=http

Let me know if you have any further questions, feel free to post back.
