So, every time I get a computer upgrade at work, or start a new job, I need to enable the query builder in Outlook. It essentially adds a third tab to the Advanced Find window. I like it because I can create nested AND/OR conditions for detailed filtering. The problem is, I do it so infrequently that I need to search for how to do it. The instructions that are out there are becoming scarce but following this will work.

Essentially: HKEY_CURRENT_USER\Software\Microsoft\Office\xx.0\Outlook\QueryBuilder
where xx.0 equals your Outlook version number.
The rub; if you launch regedit as a different elevated user, HKEY_CURRENT_USER won't be for the profile that's using Outlook. My workaround is add the regular account to local admins, edit the registry, and if your company is strict, remove the account from local admins.
Also, if you alternatively edit the appropriate USER hive instead of elevating the user, changes will not take effect until you reboot, and even then it's ify
