If your team needs to stop working by mail and excel / word / ppt, you need to start using a productivity platform.

I liked:

• Visual studio: the ability to add tasks at the feature level, and then see them in the sprints
• Planner: start to be better
•  

Online plateforms

• Visual Studio: free for small teams 5 members. Nice dashboard.
• Trello: (too simple) not really in details
• Waffle.io
• Huboard.com
• Taiga

Server install

• Odoo project management
• Orangescrum
• Tuleap

Addons

• Kanban for wordpress (limited if no pro)
• Outlook kanban
