UEFA handed Marseille a suspended one-year ban from European competition because of the behaviour of their fans.
Marseille will not be punished if they behave for a probationary period of two years, European football's governing body said on Wednesday.
Last season's Europa League runners-up have also been ordered to play their next European home match behind closed doors and have been fined €100,000.
They will also have to close sections of their Stade Velodrome stadium for their following European home match.
UEFA charged Marseille with several offences including crowd disturbances, acts of damages, setting off of fireworks, throwing of objects and late kick-off.
The offences took place in Europa League fixtures last season against RB Leipzig, Salzburg, home and away, and in the final against Atletico Madrid.
The French club, who finished fourth in Ligue 1 last season to qualify for the Europa League again, were also ordered to contact Lyon, whose stadium hosted last season's final, in order to pay for the damage caused by their fans.
UEFA also fined Liverpool €8,000 for setting off fireworks, the throwing of objects, and crowd disturbances in their Champions League semifinal home leg against Roma.
