How to Make the Timeline View Visible in Microsoft Project
Question details
Project members are unable to view the Timeline view in a shared Microsoft Project file, even though the project owner can see it.

- Product
- Microsoft Project
- Device & OS
- not provided
- Scenario
- Sharing a project plan with team members and trying to ensure they can see the configured timeline.
- Observed behavior
- The project owner can see the Timeline view normally, but team members cannot see it when accessing the shared project file created with Project Plan 3.
Ensure that all project members have the correct access permissions to the shared file and are using a compatible version of Microsoft Project or a supported project viewer to open the .mpp file.
Save the Project with the Timeline View Active
Ensure the timeline is enabled and actively displayed when saving the file so that it defaults to this view for other members.
Microsoft Project often opens files in the exact state and view they were last saved in. If the timeline was hidden or not the active pane when the file was saved, it may not display automatically for other users.
Launch Microsoft Project and open your Project Plan 3 file where the timeline is already configured.
Navigate to the 'View' tab on the ribbon. In the 'Split View' group, check the 'Timeline' box to ensure the timeline pane appears above your Gantt chart.
Click directly inside the Timeline pane to make it the active view. While it is active, go to 'File' > 'Save' (or press Ctrl+S) to save the current workspace state.
Distribute this newly saved version of the project file to your team members and ask them to open it using their compatible Microsoft Project application.

Export the Timeline as a PDF or Image
If compatibility issues persist, exporting the timeline as a static file ensures all members can view it regardless of the software they use.

Frequently Asked Questions
Why is the Timeline checkbox greyed out in Microsoft Project?
The Timeline view checkbox may be greyed out if you are currently using a view that doesn't support splitting, or if a dialog box is actively open. Switch your primary view to the Gantt Chart view first, and then try enabling the Timeline from the View tab.
Can team members view a MS Project timeline without a Project license?
Team members without a Microsoft Project license cannot natively open .mpp files. To let them view the timeline, they will need a third-party project viewer, or the project owner must export the timeline as a PDF, Excel spreadsheet, or image file.
How do I add new tasks to an existing Timeline view in MS Project?
To add tasks to your timeline, select the desired task in your Gantt chart, right-click it, and choose 'Add to Timeline'. Alternatively, you can click on the task and drag it directly into the Timeline pane.
Will exporting the Timeline to PDF preserve its original formatting?
Yes, when you export the Timeline as a PDF or use the 'Copy Timeline For Presentation' feature, it preserves the layout, bar colors, milestones, and text formatting exactly as they appear on your screen.
