This is a refresh of my old post Microsoft 365 Apps (Office 365) hantering i MECM (SCCM), or maybe I should write “a refresh of the script”.

In this post, I ensure that the Office Deployment Tool (ODT) is the latest version to support new version/function of Microsoft 365 Apps setup.
I use a modified Powershell script created by Marco Hofmann & Trond Eric Haavarstein to suit my idea.
Original script: https://www.meinekleinefarm.net/download-and-install-latest-office-365-deployment-tool-odt

What this version of the script does:

Download the latest version of the Office Deployment Tool (ODT).
Checks if it’s a newer version of the Office 365 Deployment Tool (ODT), and if it’s a newer version, extracts it to a subfolder with the version number as the folder name. If it is not a newer version, skips this step
Then copies the new setup.exe to both the folder for the source files and the application package in ConfigMgr
And for last it runs the setup.exe (with download xml-file) to download allt the Microsoft 365 Apps
