Viewing a Project Task Plan
Task Plan:
The Task plan is Read only for anyone other than the PM for that project, but details can be viewed by all. To ensure that you are viewing the current Project plan, check that it states (Published) in the title *Highlighted below.

If it doesn't show the published plan, you can select the correct plan from the Manage Plan version icon:

There are a number of Columns available, for example the Resource column may not show when you first view the Task plan. You can add columns to view by right clicking on the column header and select Resources, you can reorder the columns by clicking and dragging.
In the Plan you have access to see the Tasks, detail of the Duration and Effort (select hours or days), which resource has been assigned to those tasks and then the Gantt chart will show tasks, task links and milestones.
