Proceed with the Default Latest Version

Best for organizations without strict internal testing requirements, allowing Microsoft 365 to automatically provide the most recent security patches and features.

If your organization does not deploy a specific Office version or actively control update channels, a standard new Microsoft 365 installation will automatically receive the latest version available in the Semi-Annual Enterprise Channel.

1
Download the Office Installer

Log in to the Microsoft 365 admin center or user portal and download the default Office installation package.

2
Run the Setup

Execute the installation file without modifying any deployment configuration XML files.

3
Verify the Build

Open any Office application, navigate to File > Account, and check the 'About' section to confirm you are on the newest Semi-Annual Enterprise Channel build.

Proceed with the Default Latest Version
Automatic Updates: This method ensures you stay up-to-date with security releases (which change the build number) and feature updates (which change the version number) automatically.

Frequently Asked Questions

What is the difference between a version number and a build number in Microsoft 365?

Why does the Semi-Annual Enterprise Channel contain multiple versions?

Multiple versions remain supported simultaneously to give enterprise organizations sufficient time to test new features, macros, and third-party add-ins for compatibility before deploying them company-wide.

How often does the Semi-Annual Enterprise Channel receive feature updates?

Feature updates for the Semi-Annual Enterprise Channel are released twice a year (typically in January and July), whereas security and quality updates are provided monthly.
