Reinstall Microsoft 365 from the Office Portal

Completely removing the outdated installation and reinstalling from the official portal ensures the laptop receives the correct build associated with your business account.

Often, conflicting update channels or incorrect account associations prevent standard updates. A clean installation via the Microsoft Support tool is the most reliable way to sync your app versions.

1
Uninstall the outdated version

Download and run the Microsoft Support and Recovery Assistant tool to completely remove the existing, outdated Microsoft 365 applications from your second laptop.

2
Sign in to the Office Portal

Open your web browser, navigate to https://portal.office.com, and log in using the exact account associated with your business subscription.

3
Download and install

Click on 'Install apps' from the portal dashboard, download the setup file, and follow the on-screen instructions to install the latest Microsoft 365 build.

Installation Tip: Reboot your laptop after completing the uninstallation process and before starting the new installation to prevent leftover files from causing conflicts.

Frequently Asked Questions

Why do my two laptops have different versions of Microsoft 365?

This usually occurs if the laptops are enrolled in different update channels (such as Current Channel versus Semi-Annual Enterprise Channel) or if one device was installed using an installer from a different Microsoft account.

How can I manually check for updates in Microsoft 365 apps?

Open any Microsoft 365 application like Word or Excel, click on 'File', navigate to 'Account' (or 'Office Account'), click 'Update Options' under Product Information, and select 'Update Now'.

Will I lose my files if I uninstall and reinstall Microsoft 365?

No, uninstalling Microsoft 365 only removes the application files. Your personal documents, spreadsheets, and presentations saved locally or on OneDrive will remain completely safe and untouched.
