Fix: “We’re sorry—we’ve run into an issue” Error in Microsoft Teams

The error message “We’re sorry—we’ve run into an issue” in Microsoft Teams typically occurs due to outdated software versions, a corrupted application cache, or network connectivity issues. This message indicates that Microsoft Teams has encountered an unexpected problem preventing it from functioning properly.

Usually, this error is just a glitch and can be resolved quite easily by removing outdated, corrupted cached files. However, sometimes it may suggest a deeper issue. In any case, we have provided you with solutions for this error down below.

1. Sign Out and Sign Back In

When you’re signed in to Microsoft Teams for an extended period, it may cause some issues, including session timeouts, authentication glitches, or temporary glitches, preventing the app from functioning correctly. Signing out of your Teams account and signing back in can help resolve these issues by forcing the app to re-establish a fresh connection with Microsoft’s servers.

1. Launch Microsoft Teams on your computer.
2. Click on your profile picture or icon in the top-right corner to open the account menu.
3. From the dropdown menu, select Sign out to log out of your current session.
4. Ensure Teams is completely closed by checking your system tray. Right-click the Teams icon if visible and choose Quit.
5. Restart Microsoft Teams, click Sign in, and enter your email and password when prompted.
6. After signing back in, verify whether the issue persists.

2. Clear Microsoft Teams Cache

Microsoft Teams stores temporary cache files to improve performance by reducing load times and minimizing repeated data fetches. However, over time, these cached files can become corrupted due to software updates, improper shutdowns, or system conflicts.

When corrupted, the cache may cause unexpected errors, login failures, or synchronization issues. Clearing the Teams cache forces the application to rebuild these temporary files from scratch, eliminating any corrupted or outdated data that was causing instability.

1. Force close Microsoft Teams through Task Manager to ensure no background processes are running:
   • Press Ctrl + Shift + Esc to open Task Manager.
   • Find all Microsoft Teams processes under the “Processes” tab.
   • Right-click each one and select End task.

   

2. Press Windows + R to open the Run dialog box.
3. Type %appdata%\Microsoft\Teams and press Enter to open the Teams application data folder.
4. Select and delete all contents inside the Teams folder (files and subfolders), but don’t delete the main Teams folder itself.
5. Restart your computer to ensure all changes take effect.
6. Launch Microsoft Teams – it will rebuild its cache files automatically, which should resolve the issue.

3. Reinstall Microsoft Teams

If clearing the cache doesn’t work, the core files of Microsoft Teams may have become corrupted or outdated. Thus, removing all the problematic files related to Microsoft Teams thoroughly and reinstalling the latest version of the app will ensure a new setup with no remaining issues from the previous installations.

Uninstall Microsoft Teams

1. Press Windows + R to open the Run dialog.
2. Type appwiz.cpl and press Enter to open Programs and Features.
3. Locate Microsoft Teams, right-click it, and select Uninstall.
4. Follow the prompts to complete the uninstallation.

Delete Leftover Files

1. Press Windows + R to reopen the Run dialog.
2. Type %localappdata% and press Enter to open the Local AppData folder.
3. Find and delete the following folders:
   • Teams (contains cached data)
   • SquirrelTemp (temporary installation files)

   

4. Restart your computer to clear any lingering processes.
5. Download the latest version of Microsoft Teams from the official website.
