I am using Virtual Box 5.1 on top of Windows 7 Host OS with Ubuntu 14.04 LTS Guest OS. I have already installed VBOXADDITIONS_5.1.14_112924 and restarted the Guest machine. The folder appears as mounted underneath the Devices in Files, and it appears as shared on the Host machine.

What permissions do I need to change on my Host/Guest OS to make this shared folder work?

You have to add yourself to the shared folders group in the Ubuntu guest.

sudo adduser $USER vboxsf

Guest OS needs to be restarted after this.

If you get

'Username' is not in the sudoers file. This incident will be reported

then use

su root 

then you can proceed with as suggested by Bora.

sudo adduser $USER vboxsf
