It's amazing how often a seemingly innocent action by the user and an update for a program can affect negatively another.

When you save a message as HTML in Outlook 2007 (and 2010), Outlook creates a matching (and annoying) folder containing XML and THMX files. I'll show you how to prevent Outlook from doing this.
A security update released on October 11 2017 removes the Home Page tab from Outlook 2010, 2013, and 2016. This change was made for security reasons but because so many applications use Folder Home Pages, a registry key will re-enable it.
