OneDrive - Adding OneDrive folder shortcut
When someone shares a folder in Microsoft OneDrive, SharePoint, or Teams, you can add a shortcut to the shared folder in your OneDrive to easily find and work with the files. These shortcuts appear in OneDrive on the web, File Explorer, Teams, and in the OneDrive mobile apps.
Instructions
If you intend to delete a Shortcut from your OneDrive by deleting it from the left navigation pane in Windows, collapse the shortcut before deleting. Deleting an expanded shortcut will delete the folder and its contents for everyone, rather than remove the shortcut for that user.
In OneDrive, in the navigation pane, select Shared > With you tab.
Find the folder you want to add, and click the circle in the folder's tile to select it.
Select Add shortcut to My files. Or you can right-click the folder, and then select Add shortcut to My files.
The shortcut will now be accessible in OneDrive or in File Explorer on your computer.
In a shared library in SharePoint or Microsoft Teams, you can select Add shortcut to My files to add a shortcut to the entire library or select the specific folder you want to add, and then select Add shortcut to My files.
