Fix the “Something Went Wrong” Error in Microsoft Teams

The “Something went wrong” message in Microsoft Teams is a general error, not a diagnosis: it can come from a service outage, a sign-in problem, a network restriction, or damaged app data. Check whether Teams is having a wider service problem, then try the least disruptive fixes first: refresh or restart Teams, verify your connection and account, and update or repair the app.

What the error means

Teams uses this message when it cannot complete an action but does not show a more specific explanation. It may appear while signing in, opening a chat or meeting, loading a team, or changing settings. The same wording can therefore have several causes, and a fix that works for one person may not solve another case.

Start by noting what you were doing when it appeared and whether the problem affects one feature or all of Teams. Also check whether colleagues using the same organization are affected. If several people cannot use Teams, an organization-wide service or network issue is more likely than a problem with one device.

Try these fixes in order

1. Check the service and your organization’s notices. If other Microsoft 365 services are also unavailable, or coworkers report the same failure, wait for the administrator or service status information to clarify the issue. Reinstalling Teams will not fix a server-side outage. Work or school users can ask their IT administrator to check service health and any organization-specific notices.
2. Refresh Teams and retry once. If Teams is open in a browser, reload the page. In the desktop app, close and reopen Teams; if it remains in the notification area or menu bar, quit it there before starting it again. Save any work in other apps first. Avoid repeatedly submitting an action, such as sending a message or creating a meeting, until you know whether it already succeeded.
3. Check your connection. Open another trusted website or app. If those also fail, reconnect to Wi-Fi or wired networking and restart the router only if that is appropriate for your network. On a managed work network, a proxy, firewall, or VPN policy may affect Teams; do not try to bypass organizational controls. Ask IT whether the connection is permitted and correctly configured.
4. Confirm the account and sign-in. Make sure you are using the intended work, school, or personal account. If Teams asks you to sign in, complete the normal sign-in flow and any required organization-approved verification. If your password was recently changed, other Microsoft apps may still be signed in with old credentials; signing out and back in can refresh the session. Do not share passwords or verification codes with anyone offering to fix the issue.
5. Update Teams and restart the device. Install available Teams updates through the app or the update method provided by your organization. Also install ordinary operating-system updates when practical, then restart the device. A restart can clear a temporary app or network state, but it will not correct an account restriction or service outage.
6. Try Teams on the web or another approved device. Open Teams using a supported browser and sign in to the same account, or test on another device you are authorized to use. If the web version works while the desktop app fails, the issue is more likely local to that app installation or its cached data. If both fail in the same way, investigate the account, organization, service, or network.

Repair or reset the app

On Windows, close Teams first. Depending on your Windows version and the installed Teams app, open Settings > Apps > Installed apps, find Microsoft Teams, select the menu beside it, and open Advanced options if that option is available. Try Repair first; it is intended to fix the app without removing its data. If that does not help, Reset may clear local app data and require you to sign in again. Menu names and available controls can differ by app version.

On macOS or a mobile device, first quit or force-close Teams and install any available app update. If it still fails, use the device’s normal app-removal and reinstall process, then install Teams again from an approved source. Reinstallation can remove local app data, so make sure important work is saved or synced. On a work-managed device, check with IT before removing the app; your organization may manage its installation or configuration.

Clearing app data is not the same as deleting messages stored in your organization’s Teams service, but local settings or unsynced information may be affected. Do not delete folders or registry entries based on instructions from an unverified site. If the app offers a built-in repair or reset option, use that rather than manually removing system files.

When the problem is account or network related

A successful browser test is useful evidence, not a complete diagnosis. For example, if Teams in a browser works on your home network but not at work, the managed network may be involved. If your account works on another device but not your usual one, local app data or device configuration is more likely. If the same account fails across devices while coworkers can sign in, ask your administrator to check your account’s access and policies.

Some organizations limit which devices, browsers, networks, or Teams features can be used. A blocked sign-in, expired session, missing access, or organization policy may look like a generic app failure. Follow the organization’s normal support process rather than changing security settings or using an unapproved network to get around a restriction.

What to send IT or support

If the basic checks do not resolve the issue, useful details can help support distinguish a service problem from a device-specific one. Record:

• The exact wording of the message and what you were doing when it appeared.
• Whether it happens in the desktop app, browser, mobile app, or more than one.
• Your device type and operating system, and whether Teams is managed by work or school.
• When the issue began, whether it happens every time, and whether coworkers are affected.
• What you already tried, including whether another network or device worked.

Share screenshots only through an approved support channel, and check that they do not expose private chat content, meeting links, or other sensitive information. If Teams provides a diagnostic or feedback option, follow your organization’s guidance on whether and how to submit it.

Frequently Asked Questions

Why does Microsoft Teams say “Something went wrong” when I sign in?
Teams may be unable to complete sign-in because of a temporary service issue, an expired session, a network restriction, or an account or organization policy. Check service notices, confirm the account, and try the web version before resetting the app.

Will reinstalling Teams delete my chats?
Reinstalling generally removes the local app, not chat history stored by the Teams service. However, it can remove local settings or unsynced data, and you will need to sign in again. Save work and check with IT on a managed device before reinstalling.

Why does Teams work in a browser but not in the desktop app?
The difference points toward a desktop-app issue, such as outdated software or local app data, though it does not prove the cause. Update the desktop app, restart it, and try its built-in repair option where available.

Should I clear the Teams cache?
Only consider clearing local data after simpler steps, and use the app’s supported repair or reset controls when available. Cache locations and procedures vary between versions and operating systems, so avoid deleting files using instructions that do not match your installation.

What if Teams still shows the error on every device?
Check whether coworkers have the same problem and ask your organization’s IT team to review service health, account access, and network policies. If you use Teams outside an organization, use Microsoft’s current support options and provide the error details and troubleshooting steps you tried.
