Deploy Microsoft Teams to all devices

D.

You need to use Microsoft Intune to push Microsoft Teams to all the devices to ensure the iPhone devices and Android devices get the Teams app.

Setting Download the Teams app in the background for Skype for Business users to On would only affect the Windows computers.

To deploy Microsoft Teams to all the devices in the network, you have four possible options:

Option A: From the Microsoft Teams admin center, set Download the Teams app in the background for Skype for Business users to On. This option will automatically download and install the Microsoft Teams app in the background for all Skype for Business users. Once the download is complete, the app will prompt the user to switch from Skype for Business to Teams. This option is available in the Teams admin center under the Teams Upgrade tab. This option is the easiest and quickest way to deploy Teams, but it only works for Windows and Mac desktop clients.

Option B: Create a Group Policy Object (GPO) that contains an app package, and then link the GPO. This option is only available for Windows devices. You can create a GPO that contains the Teams app package and then link the GPO to the relevant organizational units in your Active Directory domain. This will install the Teams app on all Windows devices that are part of that OU. However, this option requires more setup time and is only applicable to Windows devices.

Option C: From the Microsoft Teams admin center, create an app setup policy that includes the Microsoft Teams app, and then assign the policy to all users. This option is available in the Teams admin center under the Teams Apps tab. You can create an app setup policy that includes the Microsoft Teams app and then assign the policy to all users. This option will install the Teams app on all devices that are signed in to Teams with a user account that is associated with the policy. However, this option requires more setup time and is only applicable to devices that support app setup policies.

Option D: From Microsoft Intune, push Microsoft Teams to all the devices. This option requires a Microsoft Intune subscription and is only applicable to devices that are managed by Intune. You can create an app deployment profile in Intune that includes the Teams app and then deploy the profile to all devices. This option provides more control and flexibility over the deployment process but requires more setup time and is only applicable to devices that are managed by Intune.

In summary, the best option to deploy Microsoft Teams to all the devices in the network depends on the devices and management tools that are available in the organization. Option A is the easiest and quickest way to deploy Teams for Windows and Mac desktop clients. Option B is only applicable to Windows devices but provides a more centralized and controlled deployment process. Option C provides more flexibility and control over the deployment process but requires more setup time and is only applicable to devices that support app setup policies. Option D provides the most control and flexibility but requires a Microsoft Intune subscription and is only applicable to devices that are managed by Intune.
