'The Office' Star -- There Will NEVER Be a Reunion ... Even For a Movie

Brace yourselves Dundler Mifflinites ... one of the stars of "The Office" -- who also ran the show behind the scenes for a few seasons -- says there will NEVER be a reunion.

Paul Lieberstein -- better known as Toby Flenderson -- was on his way out of Riva Bella in West Hollywood when we asked if there was a chance the cast would ever reunite.

The actor got right to the point without pulling any punches.
