I recently bought about a dozen Dell laptops that came with an Office 2016 trial. I have a volume license agreement with Microsoft so I chose to uninstall the trial and install our company's copy of Office 2016. the trial uninstalls without issue. our copy of Office 2016 installs without issue, including accepting the product key. the activation notification goes away (and shows the software as activated) but then reappears either after closing and reopening any Office program or after Office updates run on the computer. I have manually uninstalled the trial and my copy of Office as well as run the "remove all versions of Office" program that Microsoft provides on their site. nothing will prevent the activation request from returning at some point. what can I do to ensure the trial version is completely removed from these machines before I re-install my copy of Office?
