This is a known issue with Teams installed on some Windows 10 computers.

Hi chuying jing

From the screenshot, Teams is displaying the message that teams does not yet support personal accounts (Preview), if you want to use a personal account, you can try open Teams on the web.

This usually indicates that the installed Teams client is configured for work or school accounts (Microsoft 365/Entra ID accounts) and currently does not support signing in with the Microsoft personal account being used.

• What type of account are you trying to sign in with? Microsoft personal account (Outlook.com, Hotmail.com, Live.com, etc.) or work or school account (Microsoft 365 organization account)?
• Are you using the latest Teams client downloaded from Download Teams Desktop and Mobile Apps | Microsoft Teams

In the meantime, you can try:

If you are using a personal Microsoft account

• Use Teams on the web: https://teams.live.com
• Alternatively, uninstall the current Teams app and install the version that supports personal accounts if available in your region.

If you are using a work or school account

• Sign out of all Microsoft accounts in Teams.
• Clear the Teams cache: Close Teams completely >Press Win + R and enter: %LocalAppData%\Packages\MSTeams_8wekyb3d8bbwe\LocalCache > Delete the cache contents.
• Restart Windows and sign in again.

If the issue persists, please let me know the type of account being used and provide any specific error messages displayed after entering the credentials.

I hope this helps and look forward to your response.

Try these checks in order:

1. If Teams shows a Sign in banner, select it and complete sign-in, including any MFA prompt.
2. If no sign-in window appears, check the notification area near the clock for a Teams icon with a red dot or exclamation mark, and open the sign-in window from there.
3. Quit and reopen Teams:
   • Right-click the Teams icon in the taskbar or notification area.
   • Select Quit.
   • Start Teams again.
4. Make sure the device is connected to the network required by the organization before opening Teams. If a VPN is required, connect to it first and keep it stable.
5. Avoid switching networks while Teams is open.
6. Update Teams from profile picture > Check for updates.

If the issue started after installing the new Teams app on Windows, also check these common Windows-side causes:

7. On Windows 10, if Teams shows We've run into an issue, install WebView2 Runtime, then restart the Teams desktop app and try again.
8. If the new Teams app does not start correctly, verify that these folders are not redirected to a reparse point:
   • Cookies
   • Cache Also verify that TEMP and TMP are not set to a reparse point.
9. Verify the account has Read permission to the required AppData paths under:
   • %USERPROFILE%\AppData\Local
   • %USERPROFILE%\AppData\Local\Microsoft\Windows\...
10. Check the AllowAllTrustedApps policy if new Teams will not launch:

• Run winver and compare the build to the supported builds listed in the troubleshooting guidance.
• If the Windows build is earlier than the listed builds, check AllowAllTrustedApps under:
  • Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\AppModelUnlock
  • Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\Appx
• If AllowAllTrustedApps is 0, change it to 1 and try again.

Warning: Editing the registry incorrectly can cause serious problems. Back up the registry before making changes.

11. If the issue still persists, ask the IT admin for the Teams sign-in status code shown in the lower-left of the sign-in window, because many sign-in issues can only be resolved by the IT admin or sysadmin.
12. If the problem is specific to the new Teams launch and the local profile is damaged, a local administrator can delete the Windows user profile so it is recreated at next sign-in.
