Purchase Document E-mail Issues

Hi everyone,

Emails received from our suppliers are being flagged as phishing due to SPF spoofing detection. What would be the recommended solution in this case? Is it possible to configure an integration between Oracle Fusion and Exchange Online using native Exchange Online connectors?

Additionally, we believe that sending the Purchase Order as a compressed file may also contribute to the phishing classification. Would it be possible to send it as a PDF instead? Or is there another viable solution?

Although the subject refers specifically to purchase documents, the goal is to apply this adjustment to any email sent.
