Where to check a Microsoft 365 service problem
This sheet compares Correct resource, Wrong pick to avoid.
| Criterion | Correct resource | Wrong pick to avoid |
|---|---|---|
| Admins locked out of the admin centre entirely, suspect a sign-in outage | The public service status page (works without sign-in) | Service health dashboard, Message center feed or organization profile (all live inside the admin centre, unreachable while locked out); the Azure Service Health blade also misses it, but because it covers Azure resources, not Microsoft 365 sign-in |
