Question details

The user accidentally rejected a resource request in Microsoft Project Online and needs to change its status back to accepted or committed.

Product
Microsoft Project Online
Device & OS
not provided
Scenario
Managing resource engagements and correcting an accidental rejection in Project Online.
Observed behavior
The resource request appears red with a 'Rejected' status instead of green with a 'Committed' status, and there is no direct button to undo the rejection.
Before you start

Verify your user role (Resource Manager vs. Project Manager) in Project Online, as resolving this issue requires coordination between both parties.

Solution 1Recommended

Notify the Project Manager to Resubmit the Request

Since a rejected engagement request cannot be directly undone by the resource manager, the project manager must submit a new request.

In Microsoft Project Online, once a resource manager rejects an engagement request, the action is final. The system does not provide a direct 'undo' or 'accept' button for a request that has already been marked as Rejected (indicated by a red status). To fix this, a new request must be generated.

1
Contact the Project Manager

Reach out to the project manager responsible for the original resource engagement request and inform them that the request was accidentally rejected.

2
Create a New Engagement Request

Ask the project manager to open Project Professional or Project Online, navigate to their project schedule, and submit a new engagement request for the same resource, matching the original dates and work hours.

3
Review and Accept

Once the new request is submitted, log in as the Resource Manager, go to the Resource Center in Project Online, review the new engagement request, and click 'Accept' to change its status to Committed (green).

System Limitation: This one-way rejection process is a designed workflow in Project Online to ensure project managers are explicitly aware of all changes to their resource allocations.

Frequently Asked Questions

Can I undo a rejected resource request in Microsoft Project Desktop?

Resource engagements are primarily a feature of Project Online and Project Server. In the standalone desktop client, you manage local resources differently. However, in the online environment, a rejection cannot be undone directly by the resource manager.

Why does my engagement request show a red 'Rejected' status?

The red 'Rejected' status indicates that the resource manager has declined the requested resource allocation. Once this status is set, it requires the project manager to either adjust the project plan or submit a completely new request.

Who has the permission to submit a new engagement request?

Only the Project Manager or users with explicit project scheduling and engagement permissions can create and submit new resource engagement requests from the project schedule in Project Online.
