As previously stated, the Service Health Dashboard should be the first step when determining whether your environment is experiencing issues. The Service Health Dashboard contains the current health status of all Microsoft 365 services. Normally, services will appear as "healthy", though, the status will be updated when a service is experiencing an issue. The Service Health Dashboard will display the most detailed and comprehensive information on any ongoing or resolved issues.

You can access the Service Health Dashboard using the following steps:

1. Log in to the Microsoft 365 admin center (https://admin.microsoft.com) with an account that has either the Global Admin or Service Admin role, expand Health, and then select Service Health:

2. For services that display advisories or incidents, you can select the Advisory or Incident link next to the service, or expand the Incidents or Advisories menu option to display the relevant events:

3. If an event has a Show details link, you can click on it to review more verbose details:

Periodically monitor the Service Health Dashboard for alerts so that you can inform your users should any issues arise before your users report them.
