Did you follow the full instructions?
What does
ls -ld /home/office show?
It should be owned by uid 500 and should have at least
permissions set to 700 (rwx --- ---)
In my case, since I was granting group permissions,
I set the group ownership of the mount point to gid 777
and set the permissions to rwx for owner root, rwx for
the group and 000 for the rest.
