You can add more context by uploading an image, document or other file to your task. Microsoft To-Do supports all file types, though file uploads are limited to 25 MB per task. Files that were added in Outlook Tasks are also fully accessible in Microsoft To-Do.
To add a file, just select the desired task to open detail view, then select + Add a file and follow the prompts to upload a file from your device.
At the moment, only photos can be uploaded from our Android app. We will support uploads of all file types on Android in the future.
Please know that files are only supported within personal lists at this time. We will bring file support to tasks within shared lists with a future update.
