How to fix error message Correlation Id: dd05786e-5f5d-4b3c-9244-1a3eff416cf4 Time Stamp: 2026-11-12T13:26:08.166Z

The correlation ID cannot be repaired directly; ask your Microsoft 365 administrator to check tenant Service health first and, if no Planner-related incident is listed, submit the ID and timestamp to Microsoft Support for backend tracing.

1. Check for a tenant service incident

Your administrator should:

1. Sign in to the Microsoft 365 admin center.
2. Go to Health → Service health.
3. Review active incidents and advisories affecting Planner, Microsoft 365, Teams, or related services.
4. Check Issue history for an incident around November 12, 2026 at 13:26 UTC.
5. If nothing is listed, select Report an issue and describe the failure.

Service Health contains tenant-specific information that a public status page may not show. It can be viewed by Global, Service Support, and Helpdesk administrators.^1^

2. Have the administrator check your Planner access

If no incident is reported, the administrator should verify that:

• Your work or school account still has a Microsoft 365 license that includes Planner.
• You can open the affected plan and are still an authorized member of that plan or its associated Microsoft 365 group.
• The failure occurs when adding tasks to every plan or only this particular plan.

A qualifying Microsoft 365 license provides basic task creation and editing. Premium plans and features may require an additional Planner license.^2^

As a quick isolation test, try adding a simple task:

• In a different plan, if available.
• In Planner on the web if the error occurred in Teams, or in Teams if it occurred on the web.
• In a private browser window signed in only with the affected work or school account.

If only one plan fails, give its name to the administrator. If every plan fails, report that the problem is account-wide.

3. Escalate with the tracing details

If the problem persists, an administrator should open:

Microsoft 365 admin center → Help & support → Contact Support

Include:

• Correlation ID: [GUID]
• Timestamp: 2026-11-12T13:26:08.166Z
• Operation: Adding a task in Microsoft Planner
• Whether it fails in Planner web, Teams, or both
• Whether other users and plans are affected
• A screenshot with personal and organization information removed

The correlation ID is a request-tracing identifier, not a code that identifies the cause by itself; administrators or Microsoft Support use it with the exact timestamp to locate the failed backend request.^3^

Only a Microsoft 365 administrator can use the business support workflow. If your subscriptions were purchased through a partner, the administrator should contact that partner instead.^4^
