How to Fix Microsoft Teams Error We Ran into a Problem Reconnecting

If you get a Microsoft Teams error that says "We ran into a problem. Reconnecting...", first close Teams and restart your computer. Try to clear the Teams cache or update your graphics drivers. You can also delete saved credentials from Windows Credential Manager, or use the web version of Teams to see if the problem is with the app. Some people fix this by closing background apps or changing hardware acceleration settings. Always try these steps one at a time.

Key Takeaways

• Look at your internet connection and VPN settings first. Network problems can make Teams have reconnecting errors.

• Close Teams and open it again. Try using the web version. This can fix many usual problems fast.

• Delete the Teams cache and saved credentials. This gets rid of old or broken files that stop sign-in and connection.

• Make sure your device drivers and Windows are updated. This helps avoid problems and makes Teams work better.

• If you still have trouble after trying everything, collect logs. Then contact Microsoft Support for more help.

Microsoft Teams Error Causes

Network Issues

The Microsoft Teams error often happens when your network is weak or drops. Problems like slow internet, too many people online, or Wi-Fi problems can cause this. If your internet company has problems or your router is set up wrong, Teams may not reconnect. VPNs can also make things worse. Sometimes, VPNs slow your internet or stop Teams from talking to Microsoft servers. You can try a new network or restart your modem to help.

• Not enough bandwidth makes sound and video slow.

• Too many users make the network slow.

• Jitter and packet loss break calls and messages.

• Latency makes talking take longer.

Tip: If Teams works on your phone’s hotspot but not at home, your internet company may be the problem.

Service Outages

Sometimes, Microsoft Teams has outages. These can stop you from joining meetings or sending messages. You can check the Microsoft 365 Service Health Dashboard for updates. The dashboard shows what is broken and how long it may last.

1. Go to the Service Health Dashboard to see if Teams is down.

2. Watch for things like failed messages or missing status.

3. Use the dashboard to see if the problem is with Microsoft or your network.

Authentication Problems

Sign-in problems can cause the reconnecting error. If your password is old or you type it wrong, Teams cannot connect. Multi-Factor Authentication can also block you if it is not set up right. Conditional Access rules may stop you from signing in, especially on shared accounts.

Note: If you use VPN, sign in to Teams before you turn on VPN so you do not miss MFA prompts.

Device or App Conflicts

Your device or other apps can mess with Teams. Apps running in the background, old drivers, or wrong settings can cause errors. On Mac, startup apps can block Teams. On Windows, using compatibility mode or clearing the Teams cache can help. Tools like Fiddler can also break Teams by changing certificates.

• Close apps you do not need.

• Update your drivers and BIOS.

• Try Teams in compatibility mode if you use Windows.

You can use the Teams web version to see if the desktop app is the problem.

Quick Fixes

Check Internet and VPN

Start by checking your internet connection. Make sure your device connects to Wi-Fi or a wired network. If you use a VPN, check its settings. VPNs can block Teams or slow down your connection. Some VPNs use full tunneling, which sends all your traffic through the VPN. This can stop Teams from working. You can fix this by using split tunneling. Split tunneling lets Teams traffic go straight to the internet, making calls and meetings smoother.

Tip: If Teams works on your phone’s hotspot but not your home network, your internet provider may have issues. Try switching networks or restarting your router.

Restart Teams

Restarting Teams helps fix many problems. Close the Teams app completely. Open it again and check if you can join meetings or chat. Many users find this step solves the reconnecting error quickly.

• Close Teams from the system tray.

• Wait a few seconds.

• Open Teams again.

Note: Restarting Teams is a simple step. It does not always fix every problem, but it is a good place to start.

Use Teams Web Version

If the desktop app does not work, try the Teams web version. Go to teams.microsoft.com in your browser. Sometimes, the web app works better with certain devices or drivers. For example, a webcam may flicker in the desktop app but work fine in the web app. You may need to clear your browser cache or disable extensions like ad-blockers. Try using a different browser if you still have trouble.

1. Open Teams in your browser.

2. Sign in with your account.

3. Check if meetings and chat work.

Tip: The web version can help you join meetings if the desktop app has issues. If problems continue, try clearing cache or switching browsers.

Troubleshooting Steps

Sign Out and In

First, sign out of Microsoft Teams. Then, sign back in. This can fix reconnecting errors and sign-in problems. Signing out clears temporary data. It also resets your session. When you sign in again, Teams makes a new connection. Many people say this step fixes the Microsoft Teams error fast. If you use more than one Microsoft account, sign out of all accounts. Then, sign in again. This helps stop account conflicts.

Tip: Signing out and in can refresh your authentication. It can fix small problems without hard steps.

Clear Teams Cache

Clearing the Teams cache removes old or broken files. These files can cause connection problems. Teams keeps things like login tokens and chat history in a cache folder. If these files get old, you may see the Microsoft Teams error. You might also have trouble joining meetings.

To clear the Teams cache on Windows:

1. Close Microsoft Teams.

2. Press Windows + R to open Run.

3. Type %appdata%\Microsoft\Teams and press Enter.

4. Delete everything in the Teams folder.

5. Restart Teams.

On Mac:

• Quit Teams.

• Go to ~/Library/Application Support/Microsoft/Teams/.

• Delete the contents of folders like Cache, Application Cache, blob_storage, and others.

• Restart Teams.

• Clearing the cache often fixes login problems and missed alerts.

• Microsoft says this is a good first step for connection errors.

• Clearing the cache often can make Teams work better.

Note: Clearing the cache does not remove your messages or files. Teams will sync your data again from the cloud.

Reinstall Teams

If clearing the cache does not help, reinstall Teams. Remove the app from your device. Then, download and install the newest version from the official site. This removes broken files and gives you a fresh copy. Sometimes, reinstalling does not fix the Microsoft Teams error if your network or device has bigger problems. Still, it is important for fixing problems from bad app files.

Steps to reinstall Teams:

1. Uninstall Teams from your computer.

2. Delete the Teams folder in %appdata%\Microsoft\Teams.

3. Download the newest Teams installer.

4. Run the installer as an administrator.

5. Open Teams and sign in.

If reinstalling does not fix it, check your network or try Teams on another device.

Clear Credentials

Teams saves your login info in Windows Credential Manager. Sometimes, these get old or broken and cause sign-in errors. Clearing them makes Teams ask for your username and password again.

How to clear Teams credentials:

1. Open Control Panel.

2. Go to Credential Manager.

3. Click Windows Credentials.

4. Find all Teams entries under Generic Credentials.

5. Remove each Teams credential.

After you clear credentials, restart Teams and sign in. This can fix authentication problems and help you connect.

Update Drivers and BIOS

Old or bad drivers can make Teams disconnect or crash. Update your network, audio, and graphics drivers using Device Manager or your device maker’s website. If you see problems after a driver update, try going back to an older version.

Updating your BIOS can also fix hardware problems. Some people say updating the BIOS helped their network and made Teams work better.

Driver and BIOS update steps:

• Open Device Manager and check for updates for network, audio, and graphics devices.

• Go to your device maker’s website for the newest BIOS update.

• Follow the instructions carefully when updating the BIOS.

Caution: Updating the BIOS is hard. Follow your maker’s guide to avoid problems.

Windows Updates

Windows updates can change how Teams works. They can affect authentication and device management. Sometimes, a new update causes the Microsoft Teams error. Other times, updates fix bugs and make things safer.

• Check for Windows updates and install any patches.

• If you see errors after an update, you may need to run commands like dsregcmd /debug /leave or dsregcmd /cleanupaccounts in Command Prompt to reset device registration.

• Restart your computer after making changes.

Keeping Windows updated helps stop many Teams problems and keeps your device safe.

Advanced Solutions

VPN and Split Tunneling

You can make Microsoft Teams work better with split tunneling. This lets Teams traffic go straight to Microsoft 365 servers. It does not go through your company’s VPN. Split tunneling makes the VPN less busy. It helps calls sound clearer. Meetings run smoother because the network is less crowded.

• Split tunneling sends Teams traffic right to Microsoft 365. This helps stop slowdowns.

• You get more bandwidth for other work tasks.

• Teams calls have less lag and fewer drops.

• Security stays strong because Teams traffic is encrypted.

Tip: If you see more multi-factor authentication prompts after split tunneling, check your VPN settings. Sometimes, authentication traffic goes outside the VPN. Watch this closely.

MFA and VPN Order

Multi-factor authentication (MFA) keeps your account safe. The order you connect matters. If you start your VPN first, you may not see the MFA prompt. Teams cannot finish signing in. This causes reconnecting errors. Open Teams first. Finish MFA. Then connect your VPN. This order helps Teams sign in and lowers problems.

• Open Teams before you start your VPN.

• Finish any MFA prompts.

• Connect your VPN after Teams signs in.

Note: If you use shared or resource accounts, check if MFA is on. MFA on these accounts can block sign-in and cause errors.

Registry Edits

Registry edits can fix tough Microsoft Teams error problems. You can clear old identity data from the Windows registry. This helps when Teams keeps asking for your password or cannot connect.

How to clear Teams identity from the registry:

1. Press Windows + R and type "regedit".
2. Go to HKEY_CURRENT_USER\Software\Microsoft\Office\16.0\Common\Identity.
3. Delete any entries with your Office 365 email address.
4. Restart your computer.

Caution: Editing the registry can change your system. Always back up your registry before you make changes.

Disable ADAL

Disabling ADAL (Active Directory Authentication Library) is not good for most users. ADAL helps modern authentication like MFA and smart cards. If you turn off ADAL, you lose these features. You may see more sign-in errors. Microsoft does not support disabling ADAL. Teams authentication can break if you do this.

Tip: Only disable ADAL if your IT team tells you to. Most users should keep ADAL on for best security and connection.

New User Profile

Making a new user profile can fix deep problems. Sometimes, your Windows profile gets broken and causes Teams errors. You can make a new profile and set up Teams again. This gives you a fresh start and often fixes things other steps cannot.

• Go to Windows Settings and add a new user account.

• Log in with the new account.

• Install Teams and sign in.

Note: Save your files before you switch profiles. You may need to move documents and settings to your new account.

Browser Extensions

Browser extensions can block Teams web app features. Extensions like ad blockers or privacy tools can mess up video, audio, or sign-in. You can test this by turning off all extensions and checking Teams.

1. Open your browser’s extension panel.

2. Turn off all extensions.

3. Try Teams web app again.

4. Turn extensions back on one by one to find the problem.

• Extensions may use too much CPU or block connections.

• No single extension is always the problem, so test each one.

Tip: If Teams works after you turn off extensions, keep only the ones you need. Remove or update any that cause trouble.

When to Contact Support

Persistent Microsoft Teams Error

You have tried every troubleshooting step, but the Microsoft Teams error keeps coming back. This is the time to reach out to Microsoft Support. You should contact support if you notice these signs:

1. You checked all Teams and Exchange settings, but nothing seems wrong.

2. You ran connectivity tests, like the Teams Calendar App test, and found problems connecting to Exchange mailboxes.

3. You reviewed Exchange Web Services (EWS) access policies and confirmed Teams is not blocked, but the error still appears.

4. You made sure the EwsEnabled setting is True or Null, but Teams cannot connect.

5. All basic fixes failed, and advanced steps did not solve the issue.

If you see warnings or failed tests, prepare to escalate the problem. When you contact Microsoft Support, give them your UserPrincipalName, the exact UTC time when the error happened, and your Teams debug logs. This information helps support find the cause faster.

Collecting Logs

Support teams need detailed logs to understand what is happening. You can collect these logs yourself. Here is what you need to know:

• Teams creates two main types of logs: Support Log Files (media, signaling, platform logs) and Weblogs (application event logs).

• Logs include data for all accounts signed in on your device.

• Media and signaling logs are encrypted. Only Microsoft Support can read them. Weblogs are plain text.

• To collect logs on Windows, press Ctrl + Alt + Shift + 1. On Mac, use Option + Command + Shift + 1.

• Teams saves logs in your Downloads folder. Compress the Support Log Files before sending them.

• Log times use UTC. Tell support your local time difference.

• If you use Teams in a browser, only one weblog file is created. Use the same keyboard shortcut to collect it.

• For virtual desktops, turn on extended logging in Teams Privacy settings before you try to reproduce the error.

Collect logs right after the Microsoft Teams error happens. This gives support the best chance to help you quickly.
