Use this interactive demo to learn how to add attachments to your Microsoft To-Do tasks.

‍

Adding attachments allows you to keep relevant documents, screenshots, or project briefs right where you manage your work. Here is the simple guide:

‍

On your Microsoft 365 main dashboard, click the App launcher in the upper-left corner.
From the app list, select To Do to open Microsoft To Do.
Click on an existing task to open the detail pane on the right side of the screen.
Locate the field at the bottom of the pane labeled Add file
In the pop-up window, choose File from your device, and click open to upload.
Confirm that the file icon appears under the task name in your list view, and you’re all set.

📌 Why this matters

Adding attachments transforms scattered task management into a centralized workspace where everything you need lives in one place. Instead of hunting through email threads or file folders when a task resurfaces weeks later, you'll have immediate access to the original brief, reference images, or supporting documents.

This becomes especially powerful for recurring projects or handoffs to teammates. When you attach files directly to tasks, you're essentially creating a self-contained project capsule that preserves context and eliminates the frustration of lost or misplaced resources.
