The user needs to resolve an issue where tasks are being double-counted in a Microsoft Project master file, leading to false resource overallocations.

How to Fix Tasks Counted Twice in Microsoft Project
Product
Microsoft Project
Device & OS
not provided
Scenario
Managing tasks and resources across multiple projects using a shared resource pool and master project file.
Observed behavior
Tasks are double-counted in the master project because the same project file is linked to the shared resource pool more than once.
Before you start

Ensure you have full access to both the master project file and the shared resource pool file, and that no other users are currently editing the resource pool.

Solution 1Recommended

Break the Duplicate Link in the Resource Pool

Identify and remove redundant project connections within the shared resource pool to eliminate double-counting of tasks and resolve false overallocations.

This issue typically occurs when a project file is moved to a new folder, renamed, or deleted without first disconnecting it from the shared resource pool. Microsoft Project ends up reading the old and new file pathways as two distinct projects.

1
Open the Resource Pool

Launch Microsoft Project and open the shared resource pool file where the overallocations are occurring.

2
Access Share Resources

Navigate to the 'Resource' tab on the top ribbon, click on 'Resource Pool' in the Assignments group, and select 'Share Resources' from the dropdown menu.

3
Identify Duplicates

In the Share Resources dialog box, review the list of all connected projects. Look for the specific project name that appears twice.

4
Break the Link

Select the duplicate or outdated project entry from the list and click the 'Break Link' button to remove the connection.

Break the Duplicate Link in the Resource Pool
Best Practice: To prevent this in the future, always disconnect a project from the resource pool before moving, renaming, or deleting the file.

Frequently Asked Questions

Why are my resources showing as overallocated in Microsoft Project?

Resource overallocation happens when a resource is assigned to more tasks than their available working hours allow. However, it can also be a false positive caused by double-counted tasks if a project is linked to the shared resource pool multiple times.

How do I correctly move a project file connected to a resource pool?

Before moving or renaming a project file, open it and navigate to Resource > Resource Pool > Share Resources. Select 'Use own resources' to safely disconnect it. Once disconnected, you can move or rename the file, and then reconnect it to the pool afterward.

What happens when I break a link in the resource pool?

Breaking a link removes the connection between the specific project and the shared resource pool. The project will revert to using its own local resources, and its tasks will no longer draw from or impact the availability of the shared resources in the pool.
