How to Open a Microsoft 365 Support Ticket for a Customer Tenant
Product

Device & OS
not provided
Scenario
A partner or delegated administrator is opening a Microsoft 365 support ticket on behalf of a customer.
Observed behavior
The service request must be created in the customer tenant context; otherwise Microsoft support agents cannot run backend diagnostics for that customer tenant.
Before you start

Before you submit a request, sign in to Microsoft Partner Center and verify that you have delegated administrator permissions for the affected customer tenant. Check which tenant is active in the admin center so the service request is opened in the correct tenant context.

Solution 1Recommended

Open the service request in Partner Center and confirm the customer tenant context

Use this method when you are a partner or delegated administrator and need the request to be associated with the customer's tenant.

Partner Center keeps the partner and customer tenants separate. Opening the request from the customer's page ensures Microsoft support sees the affected tenant and can access backend diagnostics for that customer.

1
Sign in to Partner Center

Go to Microsoft Partner Center and sign in with an account that has delegated administrator permissions for the customer tenant.

2
Select the customer tenant

Select Customers from the left pane, choose the affected customer tenant, and then select Service requests.

3
Submit the service request

Choose New request, enter the issue details, and confirm that the tenant shown in the request is the customer's tenant before you submit it.

Open the service request in Partner Center and confirm the customer tenant context
Verify after submission: After you submit the request, confirm it appears under Service requests for the selected customer tenant. If it appears only under your partner tenant, reopen the request from the customer's page or contact Microsoft Partner support.

Frequently Asked Questions

How do I make sure a Microsoft 365 service request is created on the customer tenant?

In Microsoft Partner Center, select Customers, choose the affected customer tenant, open Service requests, and verify the customer tenant is shown before you submit the request.

What permissions do I need to open a support ticket for a customer tenant?

You need a partner relationship with the customer and delegated administrator permissions for the Microsoft 365, Intune, or Enterprise Mobility workload you are requesting support for.

Why does Microsoft support need the customer tenant context?

Microsoft support agents use the customer tenant context to run backend diagnostics and verify service health for the affected tenant. A request opened only under the partner tenant may limit that diagnostic access.

Can WPS Office open a Microsoft 365 support ticket?

No, WPS Office is an Office suite alternative and does not manage Microsoft 365 service requests or partner tenant administration.

What should I do if the service request still shows my partner tenant?

Reopen the request from the customer's page in Partner Center, confirm the customer tenant is selected, and if the issue continues contact Microsoft Partner support for help.
