Does Microosft Graph API or explorer supports Impersonation using SID and SMTP to access impersonated user Inbox details

Question

I am looking how we can access other user inbox details using Impersonation. I see this is possbile if we have PrincipalName and user object id details.
But is there a way i can get access these details using SID or SMTP details with Impersonation?

Answer 1

As far as I know, Graph does not support accessing user related resource using anything other than id and userPrincipalName. You can try to first retrieve one of the two fields using /users endpoint by applying on premise related fields in a filter operation.
