M365/Teams Repair

Question

Hi All

We have encountered an issue, which I was hoping someone had a solution. We deploy m365 via Intune and although we have altered the config to now allow Teams to be included in this deployment, we have many machines who had M365 deployed prior to including Teams and Teams was separately installed. We have had some issues where Teams requires a reinstall, but because the M365 install on the machine was put on before Teams was included in the M365 suite, we cannot repair/fix Teams without completely removing M365. Any suggestions on getting the Teams/M365 that is deployed with Via Intune on the machine without a complete Suite removal?

Thanks

Hi @barton, matthew

Starting in late August 2023, new Teams will automatically install with new and existing installations of Microsoft 365 Apps on Windows.

Currently, users can install the new Microsoft Teams using the "Try the new Teams" toggle switch in classic Teams or by Admins bulk upgrading directly to the computers in their organization.

Administrators may exclude new Teams from automatically installing with Microsoft 365 Apps on Windows.

Admins who don't want new Teams included with Microsoft 365 Apps on devices running Windows can follow these steps to opt out.

1. Sign in to the Microsoft 365 Apps admin center (https://config.office.com) with an admin account.
2. Go to Customization > Device Configuration > Modern Apps Settings.
3. Select Microsoft Teams (work or school), then clear the Enable automatic installation of new Microsoft Teams check box.

For the best Teams experience, we recommend leaving the setting as is.

If you've set Teams update policy to Not enabled, but users still received new Teams client with M365 Apps, please follow instructions in our How to uninstall the new Teams client article to uninstall it for your users.

Hi,

1. Deploy "Microsoft Teams (new)" as a separate Intune Win32 app

This is Microsoft’s official recommendation.

How:

Download the Teams bootstrapper installer https://learn.microsoft.com/en-us/microsoftteams/new-teams-bulk-install-client

Wrap it as a Win32 app using the IntuneWinAppUtil

Deploy it to all devices that:

have M365 installed without Teams

need Teams fixed or reinstalled

Why this works:

New Teams installs independently of the old MSI

It does not break the existing M365 suite installation

Intune can repair Teams from this standalone Win32 app moving forward

This avoids touching M365 completely.

---

2. Manually run Teams bootstrapper (one-time fix)

If you do not want to create a Win32 app:

Run on device:

msiexec /i TeamsBootstrapperInstaller-<version>.msi ALLUSERS=1

or the EXE:

TeamsBootstrapper.exe -silent

This forces new Teams installation without impacting the M365 suite.

---

3. Use an Intune Remediation Script

You can automatically detect devices missing Teams and install it.

Detection script: checks Teams presence

Remediation: installs Teams bootstrapper

This solves the issue silently.
