Understanding Microsoft 365 connection and service problems
Microsoft 365 service health can be tenant-specific, and Exchange, Teams and SharePoint may not fail together.
The checker above requests office.com from eight configured locations and shows the responses and measurement times. Compare those observations with the actual Microsoft 365 action that failed. A homepage response alone cannot verify an account, app workflow or transaction.
Distinguish Microsoft account access from mail, storage and meetings using the relevant product check: Outlook status check, OneDrive status check, Microsoft Teams status check. Compare results separately; these links do not establish a shared outage.

Microsoft 365 status information and official help
Microsoft 365 help and reporting
An authorised administrator may need tenant-specific Service Health and support.
Open office.com
Open the website in your browser and compare it with the result above.
Where to report problems with Microsoft 365
Open Microsoft 365 help / reporting. Use the provider's customer-service or account-help route for the affected product. Sign-in may be required for private account questions.
Details to include in your report
Tenant/product, affected user scope, client, UTC window and relevant incident/correlation ID.
Attach the checker’s downloaded JSON if it helps show the hostname, regional responses and original timestamps. Describe what happened in your browser or app as well. A report sent to WebsiteDown.org is not automatically forwarded to Microsoft 365.
What to check when Microsoft 365 is not working
These are troubleshooting comparisons, not claims that Microsoft 365 is currently experiencing a particular incident.
Start with the action that failed
Identify the affected app and ask an authorised administrator to compare tenant Service Health with the user report.
Narrow down the affected service
Check whether two users in the same organisation reproduce the same action on web and desktop clients.
Read the actual checker response
A 403 Forbidden or 429 Too Many Requests means the host answered but refused or limited that request. A timeout gives no HTTP response. Keep those outcomes separate and check the available-region count before treating the result as broad evidence.
How to check if Microsoft 365 is down
- Save the error. Note what you were doing and when it failed. Save unfinished work before refreshing.
- Run the office.com check. Look at the regional results and when they were checked. Checking again may return a cached result.
- Check for a service notice. Open Microsoft 365 status and check whether the named service and incident time fit your error.
- Try another browser or network. Use the specific checks above to narrow down the problem. If it continues, send the error and time through the official help link.
If Microsoft 365 Is Not Working Only For You, Start Here
Use these local troubleshooting steps after the down-check workflow when Microsoft 365 seems broken only for you. This section focuses on app, browser, account, and network fixes.
1. Compare browser sessions
Open office.com in your current browser, then test in a private window or second browser. If only one session fails, compare its account, cookie and extension context before assuming the entire service is unavailable.
2. Preserve a working account session
Keep an existing working session and preserve unsaved work. For a sign-in failure, use the official account-help route. Avoid repeated password or security resets until you confirm this is not a broader Microsoft 365 issue.
3. Try another network
If possible, compare Wi-Fi with mobile data and note which one fails. Leave any required work VPN or security settings in place.
4. Capture support-ready evidence
Save timestamp, device, network type, exact error, final URL, and status code. Use the check workflow above before contacting Microsoft 365 support.
