Welcome to Manjaro!
Have you tried following the FHS standard and mounting the external media to… well… /media! 
sudo mkdir /media/skydrive
and change your fstab line to:
//10.x.x.xx/skydrive /media/skydrive cifs username=ray,password=mypass,noauto,x-systemd.automount,x-systemd.device-timeout=10,rw
And if that wouldn’t solve your problem, use this one:
//10.x.x.xx/skydrive /media/skydrive cifs username=ray,password=mypass,noauto,x-systemd.automount,x-systemd.device-timeout=10,rw,file_mode=0755,dir_mode=0755
