Applies to

In Microsoft 365 organizations with mailboxes in Exchange Online or standalone Exchange Online Protection (EOP) organizations without Exchange Online mailboxes, the technical support resources listed in this article will help you find answers if you are having difficulty with EOP. Microsoft provides help for EOP in a variety of places and methods including self-support and assisted-support.

Self-support options

Upon logging in, the Microsoft 365 admin center provides information about the status of your organization's services. Also, the service health section shows the current status of your services, details about disruptions and outages, and lists planned maintenance times. The Microsoft 365 admin center also provides information about known issues and expected resolutions. If you're affected by a service-wide event, then you should see a communication alert (typically accompanied by a bell icon). We recommend that you read and act on any items as appropriate. For more information about the service health area, see Service health and continuity. You might be able to find more help on your own by using the tools, forums, and community sites listed here.

Assisted support from Microsoft

You can get help from Microsoft by starting a new service request within the Microsoft 365 admin center or by calling on the phone. Premier Support subscribers have extra support options.

Support for Microsoft Premier Support Subscribers

If you are an EOP customer and also have a Microsoft Premier Support contract, you can get support through the normal Microsoft Premier Support channels. This allows you to receive access to all processes and resources available to Premier Support customers, such as a Premier Technical Account Manager (TAM) and case submission. Premier Support for Microsoft Online Services extends the Premier Support framework beyond on-premises products to online services, providing you with a unified support experience across all products and services. This service helps ensure that customers can resolve issues quickly and simplifies the task of managing support for different components of an IT infrastructure.
