- Product
- Microsoft SharePoint
- Device & OS
- not provided
- Scenario
- Managing a SharePoint list and trying to completely disable attachment uploads on the Edit item form, but the field continues to display.
- Observed behavior
- The attachments field remains visible on the Edit form even after attachments are disabled in List Settings, often due to Power Apps synchronization delays or access via Quick Edit.
Ensure you have Site Owner or Full Control permissions for the SharePoint site to modify list settings, disable Quick Edit, or run PowerShell scripts.
Synchronize Form Settings and Disable Quick Edit
Update the list settings to ensure the customized form is applied, and disable alternative views where the attachment field might still be accessible.
When using customized Power Apps forms in SharePoint, changes such as disabling attachments may take several minutes to synchronize. Additionally, users might still bypass the standard form if Quick Edit or the Details Pane remains active.
Go to 'List Settings', click on 'Form Settings', and confirm that the list is configured to use the customized Power Apps form.
Wait a few minutes for the form changes to fully sync. Afterward, open the list and test the 'New' and 'Edit' forms to see if the attachment card has disappeared.
Navigate back to 'List Settings' and click on 'Advanced Settings'.
Scroll down to the 'Quick property editing' section and set it to 'No' to disable Quick Edit. Do the same for the Details Pane to prevent users from adding attachments through alternative menus.
Hide the Attachments Field via PnP PowerShell
Use a PnP PowerShell script to forcefully hide the Attachments field at the SharePoint list level if UI methods fail.

Frequently Asked Questions
Why is the attachment field still showing after I disabled it in List Settings?
If your SharePoint list relies on a customized Power Apps form, it may take several minutes for the setting changes to synchronize and publish to the live list. You may need to wait and refresh your browser.
Can users bypass the custom form to add attachments?
Yes. If 'Quick Edit' (Grid view) or the 'Details Pane' are enabled in the list's Advanced Settings, users can still access the attachment field even if it is hidden on the main Edit form.
Is PnP PowerShell required to remove the attachment field?
No, PowerShell is only an alternative method. Usually, disabling attachments in List Settings and turning off Quick Edit in Advanced Settings is fully sufficient to restrict users from uploading files.
