Blocking the New Outlook

To avoid any disruptions in your organization's workflow, you can strategically hide the new Outlook Toggle using Microsoft Intune (or via classic GPO's).

  1. Open Intune
  2. Navigate to:
    Devices > Windows > Configuration profiles
  3. Hit Create
  4. Choose:
    Platform: Windows 10 and later
    Profile type: Settings catalog
  5. Give the Policy a name (ex. WIN-OutlookNewToggle)
  6. Add settings and search for:
    New Outlook
  7. Which will show you:
    Hide the “Try the new Outlook” toggle in Outlook (User)
  8. That one you have to set to Enabled.
  9. Assign the policy to a group and that's it.

Rolling Back the New Outlook

In some cases, users may accidentally switch to the new Outlook. To help them revert back, you can create a Remediation package in Intune that rolls back the app to the classic version.
This package runs for each user and will remove the new Outlook in the user context. If you need to delete the system installed version, which for example comes with the latest Windows 11 release (23H2), head to the next section.

  1. Open Intune
  2. Navigate to:
    Devices > Windows > Scripts and remediations
  3. Hit Create
  4. Give the package a name (ex. WIN-PR-U-NewOutlookRemoval) and an optional Description.
  5. Upload both the "NEW-Outlook_uninstall-detection.ps1" and "NEW-Outlook_uninstall-remediation.ps1" from the template provided above via my GitHub.
  6. For the settings choose:
    • Run this script using the logged-on credentials: Yes
    • Enforce script signature check: No
    • Run script in 64-bit PowerShell: Yes
  7. A Scope tag is not needed in most cases.
  8. In the Assignments add a group and schedule that suits your needs.
  9. That's it. Now we can wait until the remediation runs on our devices.

Result of the Remediation

Removing the built in New Outlook

In Windows 11 versions 23H2 and later, the new Outlook app is preinstalled for all users, replacing the default Mail and Calendar apps. I guess for most organizations that not what they want. And like you probably removed the old Mail and Calendar apps in previous builds you can do the same with the new Outlook. Just run the following command during your Autopilot deployment:

Remove-AppxProvisionedPackage -AllUsers -Online -PackageName (Get-AppxPackage Microsoft.OutlookForWindows).PackageFullNameCode language: PowerShell (powershell)
