I could't join the meeting

Hi DEVRAKSHIT,

First, I want to know what system you use. In general, solving the problem in Windows is as follow:

Quick Fixes:

• Restart your computer and modem. This should fix any network connection issues.
• If signing out of your account and logging back in did not solve the problem, pursue further troubleshooting steps.

Clear Your Teams Desktop Client Cache

If the desktop client got stuck, try clearing the cache. Close Teams and follow the steps below.

1. Type %appdata%\Microsoft\Teams in the Windows Search bar.
2. Open the Cache folder and delete all the files. Check if you can join the meeting after you do that.
3. If the issue persists, continue clearing the following cache folders:
   • \%appdata%\Microsoft\teams\application cache\cache
   • \%appdata%\Microsoft\teams\blob_storage
   • \%appdata%\Microsoft\teams\databases.
   • \%appdata%\Microsoft\teams\GPUcache
   • \%appdata%\Microsoft\teams\IndexedDB
   • \%appdata%\Microsoft\teams\Local Storage
   • \%appdata%\Microsoft\teams\tmp
4. Launch Teams again. Check if the issue is gone now.

Use the Teams Web App

If this issue affects the desktop client, check if you can join the meeting using the Microsoft Teams web app. Try to access Teams in private or incognito mode.

Use the Teams mobile app if you already installed it on your phone. Alternatively, you can join up the meeting on your phone and then transfer the call to your desktop.

If this only a local glitch, you should be able to log in and join the meeting on another app or device.

Book the Meeting in Teams

Some users suggested that booking the meeting directly in Teams should prevent such issues. It appears that Outlook and Teams sometimes fail to sync all the information from the user profile.

It seems that users who booked the meeting in Outlook experienced meeting connection problems more frequently.

Update Microsoft Teams

If there’s a new Teams desktop client version available, install it and check if this quick solution did the trick. Certain features may not work properly on outdated Teams versions.

1. Click on your profile picture and click on Check for updates.
2. Install the updates, restart Teams, restart your computer.
3. Try to join the meeting again.

Whitelist teams.microsoft.com

If you’re using Mimecast URL Threat Protection, add teams.microsoft.com as an exception. This will whitelist Teams. Mimecast URL Threat Protection and other similar tools re-write the Teams URL. That’s why you can’t join the meeting. Whitelisting Teams should get the job done.

Furthermore, if you’re using an email security gateway, you may experience the same issue. This is because the tool rewrites the Teams Meeting invitation URLs for external meetings. That’s why the Join button does not work for external attendees. Or you often experience this problem with meetings organized by external parties.

On the other, internal invitations should work just fine because the email security gateway does not alter the URL.

To solve this issue, simply add an exception for https://teams.microsoft.com/. In this manner, the gateway won’t change the URL.

Reinstall the Teams App

If nothing worked, uninstall Teams.

1. Go to Control Panel, select Programs and Features.
2. Then click on Uninstall a program, and select Microsoft Teams.
3. Click on Uninstall to remove the desktop client.
4. Restart your computer and install Teams again.
