If you have a scenario where you need to map OneDrive to a drive letter, here is the steps to do that…
Note: While WebDav is supported this will work. If at any time OneDrive for Business no longer supports WebDav, this will no longer work.
- Within File Explorer, right click on your OneDrive for Business, select OneDrive for Business, then select Copy link.
- Within File Explorer, right click on Network and select Map a network drive.
- In the Folder field, right click and paste
- Make sure that Reconnect at sign-in is selected
- Click Finish
Your OneDrive will now show up as a mapped drive.
