Hi, I'm Diane and I'm happy to help you today.
Are you editing in the reading pane or in an open message? When you compose in the reading pane the message options are limited.
You can add commands to the Message ribbon - it's the first Message under the Tools group. You need to add a new group to it to add the commands to it. Or create a new tab and add the commands you need to it (but it will show all the time not just when you hit reply.)
The Review tab is only available in open messages so you'll need to find the commands and add them to the Message ribbon or a new ribbon in the main Outlook window.
Let me know how it goes, I'm here to help you further if needed.
