Removing Microsoft Office Templates

New Contributor

Does anyone have any experience (or possibly some insight) in removing Microsoft Office Templates?

Our company uses custom-created templates that feature the company logo / letterhead. The marketing department realized that the templates were created and there is a problem with the graphic. I tried using Composer to simply change the ~/UserTemplates/MyTemplates contents, but it hasn't worked. I've also tried writing a script to simply remove the two folders containing the incorrect letterheads, and that didn't work either. I'm kind of embarrassed a task so simple is hanging me up this much.

Does anyone have any ideas?
