Question details

Users are experiencing an issue where an embedded Microsoft List form successfully saves text and multiple-choice responses but fails to save uploaded photos, resulting in an error.

Product: Microsoft Lists
Device & OS: not provided
Scenario: Submitting an embedded form that requires uploading image attachments alongside standard text fields.
Observed behavior: The form accepts and saves the text data but rejects the photo uploads, displaying an error message after submission instead of securely storing the files.

Before you start

Ensure your SharePoint site has sufficient storage capacity and that the uploaded photos meet the standard file size and format requirements for Microsoft Lists.

Solution 1Recommended

Report the Bug to Microsoft Support

Since this behavior is often tied to recent SharePoint or Microsoft Lists updates, submitting a detailed support ticket is the most direct path to a permanent fix.

Microsoft frequently updates the SharePoint online environment. Occasionally, backend changes disrupt specific features like the Image column upload via embedded forms. Reporting the exact context helps the engineering team deploy a targeted patch.

Access the feedback portal

Go to the Microsoft Feedback portal or log into your Microsoft 365 Admin Center to open a support ticket.

Provide list configuration

Detail your specific list configuration, including the column types used and the exact steps taken to embed the form on your page.

Include error details

Specify the types and sizes of the photos being uploaded, and provide a screenshot or the exact text of the error code received upon submission.

Submit for investigation

Submit the feedback so the SharePoint engineering team can investigate the backend logs and provide a resolution.

Solution 2

Use Standard Attachments Instead of Image Columns

If the dedicated 'Image' column is bugging out in embedded forms, routing photo uploads through the standard 'Attachments' feature may bypass the error.

Frequently Asked Questions

What are the supported image formats for Microsoft Lists?

Microsoft Lists generally supports standard web image formats such as JPG, PNG, and GIF. Ensure your photos are not in unsupported or highly compressed formats like HEIC, which may require conversion before uploading.

Why do standard attachments work but Image columns fail in SharePoint lists?

Image columns have specific rendering, thumbnail generation, and storage mechanics in modern SharePoint experiences. Recent platform updates affecting how embedded forms process these specific column types can cause upload failures, whereas standard list attachments use an older, more universally stable upload method.

Can file size limits cause Microsoft List forms to reject photos?

Yes. SharePoint has strict attachment and file upload limits depending on your organization's site configuration. If an uploaded photo exceeds the site's maximum individual file size limit, the embedded form will return an error upon submission.
