Narrative:
After pushback for deicing, the ground crew spoke to me (first officer) that they had 2 headsets and that the other one was broken and this one did not work. It was snowing. The aircraft did overnight in bos. It did snow all night, 6-12 inches. With the pushback crew departing, the captain was now faced with having to coordinate the deicing with operations. The deicing truck departed and we couldn't hear or see any further deicing, so the captain called operations to get the required logbook information to get released from the departure station. We were very close to the helicopter landing area. In fact, there was a helicopter landing at that time lifting a lot of snow. We were pretty distant from the gate area. We cannot recall the exact exchange, but either was, or thought the captain and I were not aware that another truck had commenced operations on the tail and that deicing was in fact not completed. The captain started #1 engine and then immediately shut it down when we realized the facts. The situation was very confusing, lack of personnel, not enough headsets, no situational awareness from operations, ground, lack of communication between the ramp, the cockpit, and operations.

Narrative: AFTER PUSHBACK FOR DEICING, THE GND CREW SPOKE TO ME (FO) THAT THEY HAD 2 HEADSETS AND THAT THE OTHER ONE WAS BROKEN AND THIS ONE DID NOT WORK. IT WAS SNOWING. THE ACFT DID OVERNIGHT IN BOS. IT DID SNOW ALL NIGHT, 6-12 INCHES. WITH THE PUSHBACK CREW DEPARTING, THE CAPT WAS NOW FACED WITH HAVING TO COORDINATE THE DEICING WITH OPS.
