Question details

The user needs to add more than one file attachment to an item in Microsoft Lists but is unable to locate the necessary button in the interface.

How to Add Multiple Attachments to a Microsoft Lists Item

Product: Microsoft Lists
Device & OS: not provided
Scenario: Editing an existing list item in the modern editing form to upload additional files.
Observed behavior: The Add attachment option does not appear immediately after the first attachment is present in the modern editing form.

Before you start

Verify that you have edit permissions for the specific list item and ensure that the list owner has enabled attachments in the list's advanced settings.

Solution 1Recommended

Trigger the Add Attachment Option via the Existing File

Use this straightforward workaround to force the modern list form to display the button for adding additional attachments.

Microsoft Lists natively supports multiple attachments, but the modern interface occasionally hides the button after the initial file is uploaded. Interacting with the existing file refreshes the form's state.

Open the List Item

Navigate to your Microsoft List and click on the item you want to edit to open the modern editing form.

Click the Existing Attachment

Locate the file that is already attached to the item and click on it to open or preview the file.

Return to the List Form

Close the preview and navigate back to the list item's editing form.

Add Additional Attachments

The 'Add attachment' option should now be visible. Click it to browse and select your additional files.

Tip: If this interface behavior disrupts your workflow frequently, consider submitting feedback directly to Microsoft using the feedback tool in the app.

Solution 2

Use the SharePoint List View

Accessing the same list through SharePoint rather than the standalone Microsoft Lists app can bypass this UI glitch.

Frequently Asked Questions

Why is the 'Add attachment' button missing in Microsoft Lists?

This is a known user interface quirk in the modern list form. The button may not render initially after a file is attached, but refreshing the form's state by previewing an existing attachment usually makes it reappear.

Is there a limit to how many attachments a Microsoft Lists item can hold?

While Microsoft Lists allows multiple attachments, the total size of all attachments combined is constrained by your SharePoint environment's settings, which typically limits individual files to a generous size limit but may affect performance if overloaded.

Can I attach entire folders to a list item?

No, Microsoft Lists only supports attaching individual files. If you need to group files together, you should compress them into a ZIP file before attaching, or use a SharePoint Document Library instead of a List.
