Product
Microsoft Project Online Desktop Client
Device & OS
not provided
Scenario
Attempting to schedule or modify project tasks manually instead of using automatic scheduling.
Observed behavior
The Manual Task option is unavailable or greyed out, likely due to older compatibility modes (Project 2007) or server restrictions from Project Web App (PWA).
Before you start

Verify your project file format and ensure you have administrator privileges if you need to adjust Project Web App (PWA) server settings.

Solution 1Recommended

Save the Project in a Newer Format

Resolve the issue by saving files created in older versions into the latest Microsoft Project format, removing outdated compatibility restrictions.

If a project file is saved in Project 2007 compatibility mode, certain modern features like Manual Task scheduling are disabled by default. Upgrading the file format unlocks these features.

1
Open the Project

Launch the Project Online desktop client and open your current project file.

2
Save As Newer Format

Navigate to File, click Save As, and choose the current Microsoft Project format instead of the Project 2007 compatibility mode.

3
Verify Task Availability

Once saved, check your task settings to ensure the manual task planning option is now available.

Format Upgraded: Updating the file format ensures full access to all current Microsoft Project scheduling features.

Frequently Asked Questions

Why is the Manual Task option greyed out in MS Project?

This usually happens if the project file was saved in an older compatibility mode (such as Project 2007) or if your organization's Project Web App (PWA) server settings restrict manual scheduling.

What is the difference between Manual and Auto Scheduled tasks?

Manual tasks allow you to input any duration or date without the software automatically recalculating them based on dependencies. Auto Scheduled tasks dynamically adjust their dates based on project constraints, links, and calendars.

Do I need admin rights to change PWA task settings?

Yes, modifying Operational Policies and Task Mode Settings in Project Web App requires server administrator privileges.
