Stop the Outlook 2016 Reminders window from being “always on top”

The only unremovable Dock icon is the Finder, removing anything else should result in it staying removed. There is nothing special about Reminders and Notes, and it's always annoyed me that they put in icons for things like launchpad etc when they have system wide keystrokes or gestures for the same task.

One point to bear in mind tho, is that to prevent people accidentally removing items from the dock (accidental drags are apparently more common on Magic Mouse/Trackpad users) the distance you have to drag the icon away from the dock is significantly increased. Try it, drag an icon away, and see how far it has to travel before you get the "puff of smoke" icon that indicates it will remove it. Letting go before seeing this cursor change will just boomerang your icon back into the dock.

Office is moderately scriptable with AppleScript, so the command line interface to AppleScript can get the job done.

Try this (adapted from this blog post by Jim Shank), replacing the subject text, name and email as appropriate:

osascript -e 'tell application "Microsoft Outlook"' -e 'set newMessage to make new outgoing message with properties {subject:"My Subject"}' -e 'make new recipient at newMessage with properties {email address:{name:"John Smith", address:"jsmith@example.com"}}' -e 'open newMessage' -e 'end tell'

It's a bit lengthy, but it will get the job done. You could adapt this into a small script that you could call and provide parameters to more concisely (i.e. sendoutlook john@example.com "My Subject" "Hi John, blah blah blah") without too much work, but that's probably best left as a separate question.
