With your mobile device, you scan documents, whiteboards, and business cards in the OneDrive app.
In the OneDrive app, tap Scan .
Select Document and tap the white circle icon to scan the item.
Tip: You also have the option for multi-page scanning, which helps you combine multiple scans into a single PDF. To use that option, tap Add, then scan your next document.
To sign or draw on the image, select the Pen icon and choose a color. (If you don't like the image, tap the left arrow icon in the upper left to delete the scan and try again.)
Once you're done editing your item, tap Done (or the checkmark on Android devices), enter a file name, then tap Save (or the checkmark on Android devices).
Find the doc on your OneDrive (you may be prompted to share the latest scan) and tap the three dots to open a menu to share.
