You can do this using the Office 365 Deployment Tool:
TechNet has detailed instructions for how to use that tool (), but the basics for this situation are:
- Extract setup.exe and the configuration.xml file from the Microsoft download.
- Edit the XML file to reflect the new settings that you desire (in this case, specifying the current release channel). This is a great interactive tool for helping you build a custom configuration.xml:
- Open a command line and run: setup.exe /configure configuration.xml (you must have local admin rights to do this and browse to where the files are)
- The Office click to run installer will make the changes and notify you when complete. This will reinstall office and keep the existing setup settings in place.
Other Method you can try which made this process is easier without the need of deployment tool is utilizing Microsoft script.
