  2. All of them run two procs called 'Microsoft Teams Helper' under the standard user while Teams is running. Terams on Mac os 10.11.6 keeps crashing.
  3. Teams Keeps Closing / Crashing on Mac. All of them run two procs called 'Microsoft Teams Helper' under the standard user while Teams is running.

Troubleshoot audio

Choose the issue that best describes your situation:

Audio doesn't work with Windows 8.1

If you're running Teams on Windows 8.1 operating system, certain audio or video devices may not work if the device drivers aren't installed properly. This is a known issue on Windows 8.1, and a possible workaround is to update the device drivers to the latest version.

See Download and install drivers in Windows 8.1.

Teams doesn't recognize my audio device or you got an error that says your speaker and microphone are not working

Try the following suggestions to resolve the problem. After each suggestion, check to see if your device is working before moving on to the next one.

  • If you're on Windows 8.1, make sure your device drivers are up to date. See Download and install drivers in Windows 8.1.

  • If your audio device is connected to a USB hub, plug it directly into your computer.

  • Unplug your device, reboot and plug it back in.

  • Make sure your audio device is not disabled:

    1. Go to Start > Control panel.

    2. In Control panel, search for Sound and open it.

    3. Right-click to make sure Show Disabled Devices is checked.

    4. If your audio device is disabled, right-click the device and select enable.

  • Scan for hardware changes in Device manager:

    1. Go to Start > Control panel.
    2. Search for Device Manager and open it.
    3. Select your computer name, then select Actions > Scan for hardware changes. This will find new devices and install the drivers.
  • Download the most current drivers from the manufacturer's web site and install them.

I can't hear others

If you can't hear audio, check the following:

  • In the Teams meeting, point to the Phone/Mic icon, then select the DEVICES tab. Make sure the device you want is selected, and the volume is high. Adjust the volume using the speaker icon if needed.

  • Check the speakers and volume on your computer as well. Select the sound button on the lower-right corner of your computer, and use the sliders to change the volume of the device you want.

  • If your device is connected to a USB hub, connect it directly to your computer.

  • If you have a desk phone and the handset is on the cradle, make sure your speakerphone is on.

  • If none of these suggestions solve the problem, try using a different device, or transfer the call to another phone. For more information, see Transfer a Teams call.

People can't hear me

  • Check to make sure you're not muted. When you're muted, the Phone/Mic icon in the meeting looks like . Select the icon to unmute.

  • In the Teams meeting, point to the Phone/Mic icon, then select the DEVICES tab. Make sure the device you're using is selected.

  • Check the mic options in the Teams main window:

    1. In the Teams main window, go to Options > Audio device, and then choose the microphone you want.

    2. Use the slider to adjust the microphone volume. The blue indicator helps you choose the appropriate level for your mic as you speak.

Low call quality or choppy audio

Low audio quality might happen for different reasons. Try the following suggestions as appropriate:

  • For a quick workaround, transfer the audio to a landline or cell phone. See Transfer a Teams call.

  • If you're using wirelesses, use a wired connection for better network quality.

  • Close any programs that you aren't using.

  • If your device is connected to a USB hub, connect it directly to your computer.

  • If you're running on battery, plug your computer to a power supply.

  • Turn off your video.

  • If possible, stop sharing your screen.

  • Make sure you're not too close to your mic.

  • If you are using a noise-canceling microphone, position it approximately 1 inch away from your mouth. This filters out unwanted background noise.

  • Make a test call and adjust your mic volume and position. Select the audio icon on the lower left side of the Teams main window, then select Check Call Quality.

  • Use an audio device that's qualified for Microsoft Teams.

  • Make sure your device drivers are up to date:

    • For Windows 7, see Automatically get recommended drivers and updates for your hardware.
    • For windows 8, see Download and install drivers in Windows 8.1.

I hear echo or a screeching sound

You may even get an alert:

Check your audio - others might be hearing an echo..echo..ech..

  • If using external speakers and mic, make sure your mic isn't too close to the speakers.
  • Turn down your speaker volume to reduce the echo.
  • If you're using your webcam's microphone or if you are using your computer speakers, try using a different audio device such as a headset, handset, or standard microphone.
  • If you're in a room with several people and multiple audio devices, mute your microphone and speakers, and request others in the room to mute their audio.

Tip

If you're in a conference room, use the room's audio by adding it to the meeting. Make sure everyone in the room mutes their speakers and microphones.

  1. Pause on the People icon in the meeting, then select Invite More People.

  2. Type the conference room's phone number, and select OK. The room number is normally listed on the phone or the room information.

  3. Answer the phone when Teams calls the room.

The Teams Meeting add-in lets users schedule a Teams meeting from Outlook. The add-in is available for Outlook on Windows, Mac, web, and mobile.

Teams Meeting add-in in Outlook for Windows

The Teams Meeting add-in is automatically installed for users who have Microsoft Teams and either Office 2013, Office 2016, or Office 2019 installed on their Windows PC. Users will see the Teams Meeting add-in on the Outlook Calendar ribbon.

Note

  • There is no direct URL that links to the Teams add-in.
  • There are additional considerations if your organization runs both Teams and Skype for Business. Under some circumstances, the Teams add-in is not available in Outlook. See Upgrade from Skype for Business to Teams for details.
  • User permissions to execute the Regsvr32.exe file is a minimum requirement for the Teams Meeting add-in to be installed on the computer.
  • If users do not see the Teams Meeting add-in, instruct them to close Outlook and Teams, then restart the Teams client first, then sign in to Teams, and then restart the Outlook client, in that specific order.
  • If you are using an Office Outlook installation from the Microsoft Store, the Teams Meeting add-in isn't supported. Users who require this add-in are advised to install Click-to-Run version of Office, as outlined in Office on Windows 10 in S mode article.

Teams Meeting add-in in Outlook for Mac

The Teams Meeting button in Outlook for Mac will appear in the Outlook for Mac ribbon if Outlook is running production build 16.24.414.0 and later and is activated with a Microsoft 365 or Office 365 client subscription.​

The meeting coordinates (the Teams join link and dial-in numbers) will be added to the meeting invite after the user clicks Send.

Teams Meeting add-in in Outlook Web App

The Teams Meetings button in Outlook Web App will appear as part of new event creation if the user is on an early version of the new Outlook on the web. See the Outlook Blog to learn about how users can try the early version of the new Outlook on the web.

The meeting coordinates (the Teams join link and dial-in numbers) will be added to the meeting invite after the user clicks Send.

Teams Meeting add-in in Outlook mobile (iOS and Android)

The Teams Meeting button shows up in latest builds of the Outlook iOS and Android app.

Install Microsoft Teams On Mac

The meeting coordinates (the Teams join link and dial-in numbers) will be added to the meeting invite after the user clicks Send.

Teams Meeting add-in and FindTime for Outlook

FindTime is an add-in for Outlook that helps users reach consensus on a meeting time across companies. Once the meeting invitees have provided their preferred times, FindTime sends out the meeting invite on the user's behalf. If the Online meeting option is selected in FindTime, FindTime will schedule a Skype for Business or Microsoft Teams meeting. (FindTime will use whichever has been set by your organization as the default online meeting channel.)

Note

If you saved a Skype for Business setting in your Findtime dashboard, FindTime will use that instead of Microsoft Teams. If you want to use Microsoft Teams, delete the Skype for Business setting in your dashboard.

For more information, see Schedule meetings with FindTime.

Authentication requirements

The Teams Meeting add-in requires users to sign in to Teams using Modern Authentication. If users do not use this method to sign in, they'll still be able to use the Teams client, but will be unable to schedule Teams online meetings using the Outlook add-in. You can fix this by doing one of the following:

  • If Modern Authentication is not configured for your organization, you should configure Modern Authentication.
  • If Modern Authentication is configured, but they canceled out on the dialog box, you should instruct users to sign in again using multi-factor authentication.

To learn more about how to configure authentication, see Identity models and authentication in Microsoft Teams.

Enable private meetings

Allow scheduling for private meetings must be enabled in the Microsoft Teams admin center for the add-in to get deployed. In the admin center, go to Meetings > Meeting Policies, and in the General section, toggle Allow scheduling private meetings to On.)

The Teams client installs the correct add-in by determining if users need the 32-bit or 64-bit version.

Note

Users might need to restart Outlook after an installation or upgrade of Teams to get the latest add-in.​

Teams

Teams upgrade policy and the Teams Meeting add-in for Outlook

Customers can choose their upgrade journey from Skype for Business to Teams. Tenant admins can use the Teams co-existence mode to define this journey for their users. Tenant admins have the option to enable users to use Teams alongside Skype for Business (Islands mode).

When users who are in Island mode schedule a meeting in Outlook, they typically expect to be able to choose whether to schedule a Skype for Business or a Teams meeting. In Outlook on the web, Outlook Windows, and Outlook Mac, users see both Skype for Business and Teams add-ins when in Islands mode by default. You can configure a Teams meeting policy setting to control whether users in Islands mode can only use the Teams Meeting add-in or both the Teams Meeting and Skype for Business Meeting add-ins.

Due to certain limitations in the initial release, Outlook mobile can only support creating Skype for Business or Teams meetings. See the following table for details.

Coexistence mode in the Teams admin centerDefault meetings provider in Outlook mobile
IslandsSkype for Business
Skype for Business onlySkype for Business
Skype for Business with Teams collaborationSkype for Business
Skype for Business with Teams collaboration and meetingsTeams
Teams onlyTeams

Set whether users in Islands mode can only use the Teams Meeting add-in or both the Teams Meeting and Skype for Business Meeting add-ins

As an admin, you can configure a Teams meeting policy setting to control which Outlook meeting add-in is used for users who are in Islands mode. You can specify whether users can only use the Teams Meeting add-in or both the Teams Meeting and Skype for Business Meeting add-ins to schedule meetings in Outlook.

You can only apply this policy to users who are in Islands mode and have the AllowOutlookAddIn parameter set to True in their Teams meeting policy. For steps on how to set this policy, see set the meeting provider for users in Islands mode.

Other considerations

The Teams Meeting add-in is still building functionality, so be aware of the following:

  • The Teams Meeting add-in requires an Exchange mailbox for the primary user scheduling the meeting. Ensure that you have at least one Exchange mailbox configured in your Outlook profile and use it to schedule Teams meetings with the add-in. For Exchange requirements, see How Exchange and Teams interact.
  • The add-in is for scheduled meetings with specific participants, not for meetings in a channel. Channel meetings must be scheduled from within Teams.
  • The add-in will not work if an Authentication Proxy is in the network path of the user's PC and Teams Services.
  • Users can't schedule live events from within Outlook. Go to Teams to schedule live events. For more information, see What are Microsoft Teams live events?.

Troubleshooting

Use the following steps to troubleshoot issues with the Teams Meeting add-in.

Teams Meeting add-in in Outlook for Windows does not show

If you cannot get the Teams Meeting add-in for Outlook to install, try these troubleshooting steps.

  • Ensure the user has Outlook 2013 or later installed.
  • Make sure the user has permission to execute regsvr32.exe.
  • Ensure that all available updates for Outlook desktop client have been applied.
  • Follow these steps:
    • Restart the Teams desktop client.
    • Sign out and then sign back in to the Teams desktop client.

Note

Incorrectly editing the registry may severely damage your system. Before making changes to the registry, you should back up any valued data on the computer.

Microsoft Teams Crashes My Mac

  • Launch RegEdit.exe
  • Navigate to HKEY_CURRENT_USERSoftwareMicrosoftOfficeOutlookAddins
  • Verify TeamsAddin.FastConnect exists.
  • Within TeamsAddin.FastConnect, verify LoadBehavior exists and is set to 3.
    • If LoadBehavior has a value other than 3, change it to 3 and restart Outlook.

Delegate scheduling does not work

If your administrator has configured Microsoft Exchange to control access to Exchange Web Server (EWS), a delegate won't be able to schedule a Teams meeting on behalf of the boss. The solution for this configuration is under development and will be released in the future. As a workaround, your administrator can add the following string to the EWS Allow List: 'SchedulingService'.
