Issues with Activation

If you are having issues with running Office 365 ProPlus, such as it stating that it is in "Reduced functionality mode" or "Product Deactivated", then it is an activation issue. This is most commonly encountered when Office 365 has been disconnected from the internet for 30 days. If this happens, simply reconnect to the internet and Office 365 should restore all functionality after it becomes reactivated. You may need to restart Office 365 or the computer if the activation does not fully register. If you are still having activation problems after connecting to the internet and restarting your computer, please contact the Help Desk at 225-578-3375 or email

Other Issues

If you are having other issues with Office 365 ProPlus, such as issues with the program itself, try Repairing Office 365. You can do this by following the steps below:

  1. Go to your Control Panel by pushing the Windows key then typing "Control Panel", then selecting it.
  2. Select Programs and then go to Programs and Features. It will open up the Uninstall or change a program window.
