Processes in Microsoft 365 for setting up Office apps, redeeming product keys, and activating licenses.
Hello Don,
Which office app are you using? If the Office dashboard app (big orange icon), can you open the individual office apps from the start menu?
To fix the blank window, find the Office app in Settings > Apps and reset it. It will have the same orange icon in Apps and is fairly small. Click Advanced then Reset.
