Hello Jayne,
Thank you for posting to community forums.
From shared information I understand that you want to stop your email attachments to be uploaded to SharePoint site folder.
Before moving forward, we need more detailed information about the situation you meet. So, please kindly share with us the information below:
- Are you an owner of SharePoint site?
- Are all attachments saved to SharePoint site or only outgoing/incoming?
- Do you use Outlook (desktop/web) application or another email client?
- Have you or the site administrator set any Power Automate flows in your SharePoint site?
This information will help us to understand the problem and find a proper solution. Thank you for understanding.
Best Regards,
Igor
