Offline Office installation is perfect for installing Office on multiple PCs as you can simply copy the installer on a USB drive and use it to install Office on different PCs without having to download Office repeatedly. It is ideal as well if you are having trouble downloading Office since you can opt to purchase the USB installer to easily install Office offline. Note that internet connection is still needed to activate and update Office 365. Once activated, you can use Office 365 offline without internet connection indefinitely.

IMPORTANT

Use OneDrive at your own risk. The complimentary OneDrive included in lifetime Office 365 is subject to frequent throttling that can last days, weeks or even months. Making it unusable for long periods of time. In addition, Microsoft does not allow disconnecting complimentary OneDrive. This means that an accidental file deletion in a complimentary OneDrive on just one of these devices means permanent file deletion across all devices that use the same complimentary OneDrive. You can completely ignore these concerns if you save your files locally.

If you will go against our advice and would still use OneDrive, we require that you use a personal OneDrive instead. Unlike complimentary OneDrive, a personal OneDrive does not throttle because it is resource independent. You can also freely connect or disconnect any device of your choice to and from your OneDrive negating all our concerns mentioned above. Click here to see our guide on how to create a free personal OneDrive account and connect it with your Lifetime Office 365.

If you own previous releases of Microsoft Office below the 2016 version, it is of utmost importance that you remove them first before installing Office 365 to prevent application errors. Microsoft Office is designed in a way that it only allows one installation and once license to exist in a single device. Pirated Office should also be thoroughly removed to ensure that the new installation can connect to Microsoft’s activation servers for activation.

For PC, remove all installations first: To remove existing Office installation using the official Office removal tool, click here. Run the program and follow on-screen instructions.

For Mac, remove all installations first: Click here for a guide on how to remove Office from Mac.

After removing office licenses and uninstalling office, it is important to restart your computer.
