Microsoft is making it easier for Administrators to deploy new Outlook for organizations that are ready for it.
New installations of Microsoft 365 desktop client apps on Windows devices will include new Outlook in addition to classic Outlook. There is no change to existing installations.
When this will happen:
General availability (Worldwide): We are planning to roll out thisThis change not earlier than late February 2025. Exact timelines will be confirmed in January 2025.available with Version 2502.
What you need to do to prepare:
Administrators can configure new Microsoft 365 deployments to control which apps are included before using custom configs to do installations. Classic Outlook and new Outlook are turned on in the new default configuration, and new Outlook will be added as "on" for existing configurations unless administrators edit to exclude it. In case new Outlook is not needed yet, administrators need to specifically edit their configurations to exclude the new Outlook app in the configuration before new installations.
If administrators have blocked the "try the new Outlook" toggle in classic Outlook, that policy will not be affected by these configuration changes or installs of new Outlook. If users install new Outlook alongside classic, they will see new Outlook in the apps list in the Start menu and can use it side by side the classic app if desired.
In case new Outlook was installed and is not needed later, Administrators can continue to remove new Outlook at any time after it has been installed: Control the installation and use of new Outlook.
