Sideload Office Add-ins on Mac for testing
To see how your add-in will run on Office on Mac, you can sideload your add-in's manifest. This action won't enable you to set breakpoints and debug your add-in's code while it's running, but you can see how it behaves and verify that the UI is usable and rendering appropriately.
To sideload an Outlook add-in, see Sideload Outlook add-ins for testing.
