How to check Microsoft 365 service health

Label to let you know the admin center is changing and you can find more details at

You can view the health of your Microsoft services, including Office on the web, Yammer, Microsoft Dynamics CRM, and mobile device management cloud services, on the Service health page in the Microsoft 365 admin center. If you are experiencing problems with a cloud service, you can check the service health to determine whether this is a known issue with a resolution in progress before you call support or spend time troubleshooting.

If you are unable to sign in to the admin center, you can use the service status page to check for known issues preventing you from logging into your tenant. Also sign up to follow us at @MSFT365status on Twitter to see information on certain events.

How to check service health

  1. Go to the Microsoft 365 admin center at, and sign in with an admin account.


    People who are assigned the global admin or service support admin role can view service health. To allow Exchange, SharePoint, and Skype for Business admins to view service health, they must also be assigned the Service admin role. For more information about roles that can view service health, see About admin roles.

  2. If you are not using the new admin center, on the Home page, select the Try the new admin center toggle in the upper-right corner.

  3. To view service health, in the admin center, go to Health > Service health, or select the Service health card on the Home dashboard. The dashboard card indicates whether there is an active service issue and links to the detailed Service health page.

  4. On the Service health page, the health state of each cloud service is shown in a table format.

    View of current issues in service health

The All services tab (the default view) shows all services and their current health state. An icon and the Status column indicate the state of each service.

To filter your view to services currently experiencing an incident, select the Incidents tab at the top of the page. Selecting the Advisories tab will show only services that currently have an advisory posted.

The History tab shows the history of incidents and advisories that have been resolved.

If you're experiencing an issue with a Microsoft 365 service and you don’t see it listed on the Service health page, tell us about it by selecting Report an issue, and completing the short form. We’ll look at related data and reports from other organizations to see how widespread the issue is, and if it originated with our service. If it did, we’ll add it as a new incident or advisory on the Service health page, where you can track its resolution. If you don’t see it appear on the list within about 30 minutes, consider contacting support to resolve the issue.

To customize your view of which services show up on the dashboard, select Preferences > Custom view, and clear the check boxes for the services you want to filter out of your Service health dashboard view. Make sure that the check box is selected for each service that you want to monitor.

To sign up for email notifications of new incidents that affect your tenant and status changes for an active incident, select Preferences > Email, click Send me service heath notifications in email, and then specify:

  • Up to two email addresses.
  • Whether you want notifications for incidents or advisories
  • The services for which you want notification


Each admin can have their Preferences set and the above limit of two email address is per admin account.


You can also use the Microsoft 365 Admin app on your mobile device to view Service health, which is a great way to stay current with push notifications.

View details of posted service health

On the All services view, selecting the service status will open a summary view of advisories or incidents.

The advisory or incident summary provides the following information:

  • Title - A summary of the problem.
  • Service - The name of the affected service.
  • ID - A numeric identifier for the problem.
  • Status - How this problem affects the service.
  • Start time - The time when the issue started.
  • Last updated - The last time that the service health message was updated. We post frequent messages to let you know the progress that we're making in applying a solution.

Select the issue title to see the issue detail page, which shows more information about the issue, including the history of all messages posted while we work on a solution.

Translate service health details

Because service health explanations are posted in real-time, they are not automatically translated to your language and the details of a service event are in English only. To translate the explanation, follow these steps:

  1. Go to Translator.

  2. On the Service health page, select an incident or advisory. Under Show details, copy the text about the issue.

  3. In Translator, paste the text and choose Translate.


Most of the time, services will appear as healthy with no further information. When a service is having a problem, the issue is identified as either an advisory or an incident and shows a current status.


Planned maintenance events aren't shown in service health. You can track planned maintenance events by staying up to date with the Message center. Filter to messages categorized as Plan for change to find out when the change is going to happen, its effect, and how to prepare for it. See Message center in Microsoft 365 for more details.

Incidents and advisories

Icon Description
Information icon for advisory If a service has an advisory shown, we are aware of a problem that is affecting some users, but the service is still available. In an advisory, there is often a workaround to the problem and the problem may be intermittent or is limited in scope and user impact.
Exclamation point icon for incident If a service has an active incident shown, it's a critical issue and the service or a major function of the service is unavailable. For example, users may be unable to send and receive email or unable to sign-in. Incidents will have noticeable impact to users. When there is an incident in progress, we will provide updates regarding the investigation, mitigation efforts, and confirmation of resolution in the Service health dashboard.

Status definitions

Status Definition
Investigating We're aware of a potential issue and are gathering more information about what's going on and the scope of impact.
Service degradation We've confirmed that there is an issue that may affect use of a service or feature. You might see this status if a service is performing more slowly than usual, there are intermittent interruptions, or if a feature isn't working, for example.
Service interruption You'll see this status if we determine that an issue affects the ability for users to access the service. In this case, the issue is significant and can be reproduced consistently.
Restoring service The cause of the issue has been identified, we know what corrective action to take, and are in the process of bringing the service back to a healthy state.
Extended recovery This status indicates that corrective action is in progress to restore service to most users but will take some time to reach all the affected systems. You might also see this status if we've made a temporary fix to reduce impact while we wait to apply a permanent fix.
Investigation suspended If our detailed investigation of a potential issue results in a request for additional information from customers to allow us to investigate further, you'll see this status. If we need you to act, we'll let you know what data or logs we need.
Service restored We've confirmed that corrective action has resolved the underlying problem and the service has been restored to a healthy state. To find out what went wrong, view the issue details.
False positive After a detailed investigation, we’ve confirmed the service is healthy and operating as designed. No impact to the service was observed or the cause of the incident originated outside of the service.
Post-incident report published We’ve published a Post Incident Report for a specific issue that includes root cause information and next steps to ensure a similar issue doesn’t reoccur.
