When someone shares a file or folder with you, you can view it under the Shared tab of the OneDrive Web app (portal.office.com).
Although this feature is not available for shared individual files, you can sync shared folders to your OneDrive desktop app by creating a shortcut to your My Files section.
1. Login to portal.office.com and select the OneDrive Web app (cloud icon)
2. Click on the ‘Shared’ tab on the left.
3. Hover over the folder you would like to sync, and click on the 3 dots to access the dropdown menu.
4. Click ‘Add Shortcut to My Files’.
5. You may see a pop-up in the top right indicating ‘Added 1 Shortcut to My Files’
6. Click on the My Files tab on the left, confirm you can view the folder there.
7. Open the OneDrive desktop app. Your folder will appear with a link icon indicating it’s a linked folder shortcut.
8. You can still copy, move, edit, rename and delete anything in the folder.
Note: This option is not available for shared individual files or images. You can view these shared items using the OneDrive Web app.
