How to fix Microsoft 365 not working
Microsoft 365 is up on our end, so if it won't work for you, the problem is most likely on your side. Work through these in order:
Your browser tries to reach microsoft.com over your own connection, right now. Nothing is sent to us or stored.
Check the service status page
Open https://status.cloud.microsoft/ first. A known incident there means the outage is not yours to fix, so you can stop reading; no incident listed points to your device, your account or your network.
Restart the app and sign in again
Quit Word, Excel, Outlook or Teams completely, then reopen it. Sign out from File > Account and sign back in; a stale token behind the blank pane, the endless spinner or the 'We couldn't sign you in' error clears once the app collects fresh credentials.
Verify your license and account
Go to File > Account and check that your name and license appear, and that the product reads as activated. 'Unlicensed Product' or 'Account Error' means the sign-in went stale; select Sign out, close the app, reopen it, and sign in with the work or school account tied to your subscription.
Repair the Microsoft 365 install
Settings > Apps > Installed apps holds the repair tools on Windows: find Microsoft 365, pick Modify, then run Quick Repair. If that fails, run Online Repair, which downloads fresh files and leaves your documents alone. On a Mac, quit every Office app and check Help > Check for Updates; if the build is current and the app still misbehaves, uninstall and reinstall it.
Common Microsoft 365 error messages
What each message means and what to try. The wording can differ a little between app versions.
-
Access denied. You do not have permission to perform this action or access this resource.
- Means
- Your account lacks permission for that item.
- Fix
- Ask the site owner or an admin for access. If another account has access, sign in with that one.
-
Sorry, this site hasn't been shared with you.
- Means
- You don't have access to that site.
- Fix
- Use the request access link on the page. Or contact the site owner and ask them to share it.
-
The connection to Microsoft Exchange is unavailable. Outlook must be online or connected to complete this action.
- Means
- Outlook can't reach the mail server, so it can't complete the action.
- Fix
- Check your network. Make sure Outlook isn't set to Work Offline, and if other apps are also failing, wait and try again.
While Microsoft 365 is down: what to use instead
- Browser versions If the desktop apps hang at sign-in, try Word or Outlook in a web browser, because the web and desktop versions sometimes fail separately.
- Synced files on your computer Files that OneDrive has already synced to your device still open from File Explorer or Finder while the cloud side is unreachable.
- Google Docs and Sheets Upload a Word or Excel file there when a deadline won't wait.
- Zoom or a phone call When Teams meetings refuse to connect, send a Zoom link or just call people so the meeting can go ahead while you wait for Teams to recover.
Fix Microsoft 365 on Windows, Mac, Android and iPhone
Microsoft 365 on Windows
- Fix
- Run the Quick Repair tool for Microsoft 365 from the Windows Settings 'Apps' menu to fix corrupted files. If the service is online, try signing out and back into your Microsoft account within the app.
- Check
- Check the official Microsoft 365 Service Health dashboard or the @MSFT365Status social media account to see if there is a known cloud outage. You can also try accessing Microsoft 365 via a web browser to see if the issue is isolated to your Windows desktop apps.

- Fix
- Force quit the unresponsive Microsoft 365 app and check the Mac App Store for any pending updates. If connection issues persist, try signing out and back into your account to refresh the credentials.
- Check
- Verify if Microsoft 365 is experiencing a service disruption by checking the official Microsoft Service Health status page. If the web version works but your Mac apps do not, the issue may be local to your macOS device.

- Fix
- Clear the cache for the Microsoft 365 app in your Android settings, or reinstall it from the Google Play Store. Make sure the app has permissions to use background data and that your internet connection is stable.
- Check
- Check the Microsoft 365 Service Health page using your mobile browser to see if there is an active server outage. If the web service is up but the Android app fails to sync, it may be a local app or connection issue.
Microsoft 365 on iPhone and iPad
- Fix
- Reinstall the Microsoft 365 app from the App Store to clear corrupt temporary files. You can also toggle Wi-Fi off and on, or ensure that cellular data access is enabled for the app in your iOS Settings.
- Check
- Visit the Microsoft 365 Service Health portal on Safari to check for widespread cloud outages. If the portal is active but your iOS app fails to connect, check your cellular data settings or the App Store for outage reports.

Problems at the same time as Microsoft 365
Since 5 October, all 10 of Microsoft 365's spikes in problem reports overlapped a spike at another service.
When several services get problem reports at once, something they share, such as a cloud host or a network, can be the real cause. Matching times alone do not prove it.

What happens when Microsoft 365 goes down
Microsoft 365 is a subscription bundle of Office apps, email, file storage, and chat that workplaces, schools, families, and clubs use every day. An outage can interrupt a deadline or a support shift when Outlook, Teams, Word, or OneDrive will not load or save.
Sign-in breaks first. You might loop back to the login page or see a service unavailable message when Outlook or Teams opens, and once you are in, Teams messages can fail to send while Outlook stops fetching new mail, calendar updates stall, and calls drop. File work breaks in patches too: Word or Excel can refuse to open a document from SharePoint or OneDrive, and saved changes can sit on 'Uploading' or vanish from the sync queue. These problems are often partial, hitting one region or one app while the rest works.

Checked from our server in Frankfurt, Germany, 28 h ago, for www.microsoft.com. A service behind a CDN answers from many data centres, usually the one nearest to you, so these addresses are where its traffic enters, not where its own servers stand. Visitors elsewhere may see different addresses.
Checked from 11 places around the world
None of check-host.net's 11 servers got an answer from www.microsoft.com (connection timed out), but our own check from Frankfurt did, 28 h ago. That usually means the site drops automated checks from those servers, not that it is down.
Checked with check-host.net from 11 cities 28 h ago, for www.microsoft.com.

How we track Microsoft 365
The status on this page comes from user-submitted problem reports for Microsoft 365, counted in 15-minute windows over the last 24 hours. Each window is compared with the normal level for Microsoft 365, so a few complaints on a quiet day don't trigger anything, but a sudden jump well above normal does.
When reports climb well above normal, the status here changes to partial outage or major outage and the chart moves with it. This is separate from Microsoft 365's official status page: user reports tend to show a problem early, while the official page confirms the cause. If the two disagree, check both.
