Hi @hong_yip
Could you share me the data structure of SMTP attachment in the following way?
Because of restrictions, I can’t test SMTP, so I use Send an email (V2) as an example.
Feel free to fill in the contents of Attachment Name -1 and Attachment Content -1, and then click this icon



This is the attachment data structure of Outlook. Please share the data of SMTP with me, thank you.

Best Regards
