Additional meeting and call-related features and issues within Microsoft Teams for business
Hello @René Moniz,
Good day! Thank you for posting your valuable question on the Microsoft Q&A forum.
Based on your description, I understand that you are encountering an error message in the New Microsoft Teams app stating “We’ve run into an issue – Oops, something went wrong!” along with a code referencing conversationId. This typically indicates a problem with account loading, cache corruption, or the Teams runtime environment.
Please let me know if I misunderstood any part of your issue or if there are additional details you’d like to share.
To help us provide the most accurate and effective solution, could you please share a bit more information about your setup?
- What operating system are you on, Windows 10 or Windows 11?
- Are you signed in with multiple accounts (work, school, or personal), or just one?
- Does Teams Web (https://teams.microsoft.com) work normally for you?
- Does the error appear immediately when opening Teams, or only after loading chats or switching accounts? Is this your first time open Teams or it launched successfully before?
- Are you using any VPN, proxy, or corporate network settings that could affect connectivity?
- Have you recently updated Teams, changed accounts, or switched organizations (guest tenants)?
This additional context will help us understand your environment and identify whether the issue is related to cached data, account profiles, network conditions, or the Teams runtime components.
In the meantime, here are a few basic steps you can try:
1. Fully Quit Teams
Before applying any fix, make sure Teams is completely closed:
- Right‑click Taskbar > Task Manager
- End all processes named:
- Teams.exe
- ms-teams.exe
- TeamsWebView*
Sign out from all accounts if the button is available on the error screen.
2. Clear Microsoft Teams Cache
- Navigate to your Taskbar and look for the Microsoft Teams icon. Right-click the icon and choose Quit. This will force the Teams app to quit.
- Next, copy and paste the following location into File Explorer: %appdata%\Microsoft\Teams, and delete the contents of the entire folder.
- Restart Microsoft Teams by opening the application and logging back in.
3.Repair or Reset from Windows Settings
- Settings (Windows + I) > Apps > Installed Apps
- Search Microsoft Teams
- Click on the three dots > Advanced options
- Choose Repair
- If the issue continues, select Reset
- If neither option resolves the problem, proceed with Uninstall
4.Reinstall Teams:
- Fully uninstall Microsoft Teams from your device
- Download the latest version from Download Teams Desktop and Mobile Apps | Microsoft Teams and reinstall it.
Please let me know the result so I can help you troubleshoot further if needed.
