Aircraft X on Date was boarded with 2 passengers and taxied out. Apparently the night before the same plane was cancelled due to fumes. On [that] morning we (crew of 5) were deadheaded to ZZZ to take the same aircraft to ZZZ1. I do not understand who determined the aircraft was now safe to fly. The FO (First Officer) and FA's (Flight Attendants) smelled a strange musty odor on taxi out and returned to the gate. We did not take the plane to ZZZ1.The decision made that the plane was indeed safe to fly when there were still fumes in the cabin.
A321 Flight Attendant reported a 'strange musty odor' during taxi. Flight returned to gate and did not take aircraft to destination.
