Que deviennent mes plannings quand Project Online ferme ?

Apres le 30 septembre 2026, vous n'atteignez plus le service ni les donnees qu'il contient : les plannings doivent donc bouger avant cette date. La destination indiquee par Microsoft est Planner and Project Plan 3, a 30 dollars par utilisateur et par mois en paiement annuel.

Lesquels de ces outils ouvrent vraiment un fichier .mpp ?

Moins que vous ne le pensez, et certains n'en importent qu'une partie. Utilisez le filtre « Ouvre les .mpp » du tableau : il est calcule depuis les cellules elles-memes, il ne peut donc pas s'en ecarter.

Y en a-t-il un vraiment gratuit ?

Plusieurs outils ont un plan gratuit, mais gratuit signifie rarement gratuit pour un vrai planning : deux postes, trois tableaux, un projet. Activez le filtre « A un plan gratuit » puis lisez la derniere ligne, qui dit ce que chaque plan gratuit contient reellement.
