Troubleshooting

How to fix Microsoft Outlook not working

Microsoft Outlook 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 outlook.com over your own connection, right now. Nothing is sent to us or stored.

  1. Restart Outlook in Safe Mode

    Hold down Ctrl while launching Outlook to open it in Safe Mode, which disables add-ins that might be causing crashes or sync issues. If the problem disappears, go to File > Options > Add-ins and disable extensions one by one to find the culprit.

  2. Check your mailbox storage and archive old items

    Outlook slows down or stops syncing when your mailbox nears its size limit. Go to File > Mailbox Settings > Mailbox Cleanup to see how much space you're using, then archive or delete old messages and empty your Deleted Items folder.

  3. Repair your Office installation

    Corrupted files can break mail delivery, calendar sync, or search. Open Settings > Apps > Installed apps, find Microsoft 365 or Office, click the three dots and choose Modify, then run Quick Repair first; if that fails, run Online Repair.

  4. Remove and re-add your email account

    A corrupted profile causes login loops and sync failures that other fixes won't touch. Go to File > Account Settings > Account Settings, select your account and click Remove, then restart Outlook and add the account again using the same credentials.

Error messages

Common Microsoft Outlook error messages

What each message means and what to try. The wording can differ a little between app versions.

  • Cannot start Microsoft Outlook. Cannot open the Outlook window. The set of folders cannot be opened.

    Means
    The app quits while it launches because it cannot read the data file that holds your mail, calendar and contacts.
    Fix
    Close the app and reopen it, since a stuck profile load often clears on the second try. If it does not, repair the Office install from Windows settings, and when that fails too, build a new Outlook profile and connect the same mailbox to it.

  • The connection to Microsoft Exchange is unavailable. Outlook must be online or connected to complete this action.

    Means
    The app cannot reach its mail server, so it will not send, sync or open items that live on the server.
    Fix
    Check your network connection and confirm the server address in your account settings. A laptop that moved between networks often needs a restart of the app before it reconnects.

  • Your server administrator has limited the number of items you can open simultaneously. Try closing messages you have opened or removing attachments and images from unsent messages you are composing.

    Means
    You have more items open at once than the mailbox allows, which tends to happen with large attachments and many separate windows.
    Fix
    Close the windows you are not using and send or delete the drafts holding big attachments. Emptying the Deleted Items folder frees room as well.

  • The operation failed. An object cannot be found.

    Means
    The app looked for a folder, contact or address that is no longer in the mailbox.
    Fix
    Restart the app and repeat the same action from a different folder. If it keeps happening, repair the mailbox file or rebuild the profile.

While Microsoft Outlook is down: what to use instead

  • Outlook on the web When the desktop or mobile app sits on 'Trying to connect' or stops syncing, sign in through a browser; the web version often loads your inbox and calendar even when the app won't.
  • Apple Mail or the Gmail app If only the Outlook mobile app is stuck, add your Microsoft account to one of these, which can still fetch your mail as long as the servers behind it are up.
  • Microsoft Teams chat For urgent work messages, Teams reaches the same colleagues, though it runs on the same Microsoft 365 back end and can go down with it.
  • Official status page Check it before you remove and re-add your account, since a posted incident means the fault sits on Microsoft's side.
Your device

Same time

Problems at the same time as Microsoft Outlook

Since 5 October, all 2 of Microsoft Outlook'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.

About

What happens when Microsoft Outlook goes down

Microsoft Outlook is an email and calendar client that handles messages, schedules, contacts and tasks for hundreds of millions of people in corporate environments and personal accounts. When it goes down, meetings vanish from calendars, inbox syncs freeze, and teams lose their primary channel for both internal communication and external correspondence.

Problems often surface as authentication loops that refuse credentials, mail stuck in the outbox that won't send, or calendar events that disappear or fail to update across devices. Mobile apps tend to lose sync before the web interface does, though sometimes the web client throws generic server errors while the desktop app still works. Outages can hit one region while others stay online, or they can knock out specific features like search or shared mailboxes while basic sending still functions. The desktop client sometimes caches enough to let you read old mail, but composing or replying typically requires a live connection to Microsoft's servers.

Questions

Microsoft Outlook FAQ

Is Microsoft Outlook down right now?
The status at the top of this page shows whether user problem reports are above their usual level over the last 24 hours. You can also check the official status page at https://status.cloud.microsoft/ for Microsoft service details. To tell if it is only on your side, try webmail in another browser and check whether other sites load fine.

Why does Outlook keep saying 'Something went wrong' when I sign in?
That message usually means the login did not finish, so try again after clearing cookies or using a private window. If it only happens in one browser, your extensions or cached data are likely the cause. Switching to the Outlook mobile app can also reveal whether the account itself is fine.

Why are my Outlook emails stuck in the Outbox?
A message stuck in the Outbox often means the app thinks you are offline or the attachment is too large. Reopen Outlook, switch from Work Offline to online, and resend. On mobile, force-close the app and try again on Wi-Fi.

Why is Outlook not syncing my Exchange account?
Outlook may stop syncing when the connection to the server is blocked or the password changed. Remove and re-add the account, then restart the app. If it still fails, check the server settings in your account details.

Why can't I open shared mailboxes in Outlook?
Shared mailboxes can disappear when permissions are not granted or the account needs a fresh sync. Ask the admin to confirm your access, then sign out and back in. On desktop, create a new profile if the folder still does not appear.

How we track Microsoft Outlook

The status on this page comes from user-submitted problem reports for Microsoft Outlook, counted in 15-minute windows over the last 24 hours. Each window is compared with the normal level for Microsoft Outlook, 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 Outlook'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.
