Here are some steps you can take to resolve this issue: 1. Check the Role Permissions: Ensure that the user's role has at least Edit level of Document and Files Permission under the lists subtab. If the permission is set to 'Create', try updating it to 'Edit'. 2. Check the Custom Record Permissions: If the issue is happening on a custom record, check if the user has 'Edit' access to that custom record. Custom records have a Permissions field which can override the Role permissions. 3. Check the Folder Permissions: The issue might be related to the folder's restrictions. Check if the folder is restricted for a certain group of people or marked as private. Also, ensure that the role has permissions to edit/create files in that folder. 4. Check the User's Preferences: Go to Set Preference > Custom Preference > tick Enable Drag and Drop preference. 5. Check the Customer and Supplier Permissions: In some cases, the issue might be due to the user only having 'View' permission on customers and suppliers. If that's the case, try updating the permissions. Remember, the user should be able to manually attach files without using the drag and drop function. If they can't, there might be other issues at play. If all else fails, you might need to create a workflow action script to include the drag and drop feature in a workflow.
