Fix Project Tasks Missing in Project Web App: GeneralQueueJobFailed Error
Question details
The user needs to recover a missing Project Tasks list in Project Web App that failed to synchronize due to a specific queue error.
- Product
- Project Web App (Microsoft 365)
- Device & OS
- not provided
- Scenario
- Importing or viewing project tasks lists in Project Web App.
- Observed behavior
- The Project Tasks list is completely missing, and the backend queue displays a GeneralQueueJobFailed error for ProjectImportTaskList.ProjectImportTaskListMessage.
Before escalating this issue, ensure you have gathered the exact JobUID, CorrelationUID, and timestamps of the failed queue jobs from your PWA settings, as Microsoft Support requires these for diagnostics.
Gather Diagnostic Information and Escalate to Microsoft Support
Because this error involves tenant-level backend synchronization failures, standard users cannot resolve it directly. It must be investigated by Microsoft Support using specific error logs.
The GeneralQueueJobFailed error triggered during a ProjectImportTaskListMessage indicates a breakdown in the backend data import process. Resolving this requires tenant-level administrative privileges and server-side log analysis.
Navigate to your Project Web App (PWA) Settings menu and click on 'Manage Queue Jobs' under the Personal or Administrative settings.
Find the failed 'ProjectImportTaskList' job in the queue. Click on the error details and copy the exact JobUID and CorrelationUID.
If you are the SharePoint or Project Server administrator, export the Unified Logging Service (ULS) log entries that match the collected CorrelationUID for the time of the failure.
Log into the Microsoft 365 Admin Center. Navigate to 'Support' > 'Help & support' and open a new service request.
Provide the Microsoft Support engineer with the JobUID, CorrelationUID, and the ULS log information you collected so they can investigate the tenant-level failure.

Frequently Asked Questions
What causes the GeneralQueueJobFailed error in Project Web App?
This error typically occurs when the ProjectImportTaskList message fails to process correctly in the server queue. It is often caused by data corruption, list schema mismatches, or backend synchronization timeouts within the Microsoft 365 environment.
Where can I find the JobUID and CorrelationUID?
These unique identifiers can be found in the PWA Settings under 'Manage Queue Jobs'. By clicking on the specific failed job, you can view its detailed properties and error IDs.
Can a standard user fix the missing Project Tasks issue?
No. Because this specific queue failure requires backend server log analysis (ULS logs) and tenant-level support requests, you must contact your Microsoft 365 Tenant Administrator or IT team to resolve it.
What are ULS logs and why are they needed?
Unified Logging Service (ULS) logs record detailed backend events and errors for Microsoft SharePoint and Project Server environments. They provide Microsoft Support engineers with the precise technical context needed to pinpoint why a queue job failed.
