cannot connect to Teams meetings

Hi @Max Gazzardi Bilingual Solutions,

I hope you're doing well today.  

To better assist, could you please confirm the exact error message you see when trying to join the meeting?

In the meantime, you can try the following steps:

1/ Try a different join method right away

If you're using the desktop app, switch to the web app or vice versa. You can also try joining via InPrivate/Incognito mode while signing in with the same account.

2/ Ensure you're using the correct account

Make sure you're signed in with the same work or school account that received the meeting invitation, as mismatched accounts can cause join issues or looping behavior.

3/ Use the Teams mobile app (for mobile devices)

If you're on a phone or tablet, avoid joining through a browser. Teams meetings are not supported on mobile browsers, please use the Teams app instead.

For more information, please refer to I can't join a meeting in Microsoft Teams

4/ Clear Teams cache

For Windows:

• If Teams is still running, right-click the Teams icon on the taskbar and select Quit.
• Press Windows + R to open the Run dialog box.
• In the Run dialog box, enter the following path and click OK: 

    %userprofile%\appdata\local\Packages\MSTeams_8wekyb3d8bbwe\LocalCache\Microsoft\MSTeams
  

• Delete all files and folders in this directory.
• Restart Teams.

For macOS:

• If Teams is still running, right-click the Teams icon in the dock and select Quit, or press Command + Q.
• Open Finder > go to Applications > Utilities > double-click Terminal.
• Enter the following commands, pressing Return after each one:

    rm -rf ~/Library/Group Containers/UBF8T346G9.com.microsoft.teams 
    rm -rf ~/Library/Containers/com.microsoft.teams2
  

• Restart Teams.

For reference: Clear the Teams client cache - Microsoft Teams | Microsoft Learn  

5/ Restart and update Teams

Close and reopen the app first. If the issue continues, check for updates or reinstall Teams.

For more details: Teams for Education is not working.

6/ Contact your IT admin

If this issue continues across multiple meetings or starts to affect your ability to join calls, I recommend reaching out to your IT administrator.

Your IT admin can create a support ticket through the Microsoft 365 Admin Center by following the steps here: Get support - Microsoft 365 admin | Microsoft Learn .

Raising a support ticket allows Microsoft support engineers to investigate the issue in more depth. They can check backend service health, review meeting and account logs, identify any tenant-level or policy-related problems (such as conditional access, meeting policies, or licensing), and determine whether this is part of a wider service issue affecting multiple users.

If you’re unsure who your IT admin is, you can find guidance here: How do I find my Microsoft 365 admin? - Microsoft Support.

Note: We appreciate your understanding regarding the scope of support available through this forum. As moderators, our role is to provide general guidance and assist with common troubleshooting steps. While we do not have access to internal systems or administrative tools required to resolve account-specific or backend-related issues but we’ll continue doing our best to support you within the scope of our responsibilities.

I hope this helps you move forward. If you have any questions or need further clarification, please feel free to reach out. I’ll be happy to assist further.

Thank you for your patience and understanding, and I look forward to supporting you.

Hi @Max Gazzardi Bilingual Solutions,

Thank you for the additional details.

Based on your description (works on iPhone and browser, but not on the Mac app and previously “Join without account” also stopped), it does strongly suggest a local macOS profile or Teams client issue, rather than a problem with your account or the meeting itself.

Please try to create a temporary new macOS user to isolate whether your current profile is causing the issue:

• Go to System Settings > Users & Groups
• Add a new local user
• Sign out and log in to the new user profile
• Open or install Teams
• Try joining one of the affected meetings

If it works in the new profile, the issue is almost certainly tied to your original macOS user environment (e.g., cache, Keychain, identity tokens, or local app data).

Here are a few workaround options you can try in the meantime:

1/ Join using Meeting ID & passcode

Ask the meeting organizer for:

• Meeting ID
• Passcode

Then in Teams: go to Calendar > “Join with an ID”

This can bypass issues related to how meeting links are handled on Mac.

2/ Force the browser instead of the Teams app

Since Teams on the web works for you, you can use this reliably:

• Open the meeting link in Safari/Chrome/Edge
• When prompted to open Teams > click Cancel
• Select “Continue on this browser”

If it still redirects to the app:

• Clear site data/cookies for:
  • teams.microsoft.com
  • login.microsoftonline.com
  • office.com
  • microsoft.com
  • Then reopen in a private/incognito window.

If you’re working as a freelancer without an IT administrator, and the issue only occurs with meetings from those two companies, it may be helpful to reach out to their IT or admin teams and ask them to verify:

• External access settings
• Meeting policies (such as anonymous join and lobby configuration)

Regarding the May 18 update, there are no widely reported issues affecting all users at this time, and there’s no confirmed indication that this is a known bug.

If you have any questions or need further assistance, please don’t hesitate to let me know.

Thank you for your understanding and cooperation.
