How do you use the right click function in Outlook Email?
Hi @botey Welcome to the forum! 
For Outlook desktop, note that the right click function is not available in the Text Blaze Desktop apps. You can instead use the Assistant by invoking it with the Ctrl-Shift-/ hotkey (you can also change this shortcut yourself).
Inside the Chrome browser, Outlook Web overrides the right click menu (and presents its own custom right click menu), so Text Blaze Chrome extension's menu does not show there. You can also use the Assistant to insert snippets in this textbox, view this video to learn more.
Let me know if it works for you.
