To remove an add-in that you've previously sideloaded on Windows, Mac, or iOS, you need to clear the Office cache on your computer.

Additionally, if you make changes to your add-in's manifest (for example, update file names of icons or text of add-in commands), you should clear the Office cache and then re-sideload the add-in using an updated manifest. Doing so allows Office to render the add-in as it's described by the updated manifest.

If you only want the sideloaded add-in to reflect recent changes to its HTML or JavaScript source files, you shouldn't need to clear the cache. Instead, just put focus in the add-in's task pane (by clicking anywhere within the task pane) and then press Ctrl+F5 to reload the add-in.


To clear the Office cache using the following steps, your add-in must have a task pane. If your add-in is a UI-less add-in -- for example, one that uses the on-send feature -- you'll need to add a task pane to your add-in that uses the same domain for SourceLocation, before you can use the following steps to clear the cache.

  1. Install the Microsoft Edge DevTools.

  2. Open your add-in in the Office client.

  3. Run the Microsoft Edge DevTools.

  4. In the Microsoft Edge DevTools, open the Local tab. Your add-in will be listed by its name.

  5. Select the add-in name to attach the debugger to your add-in. A new Microsoft Edge DevTools window will open when the debugger attaches to your add-in.

  6. On the Network tab of the new window, select Clear cache.

  7. If completing these steps doesn't produce the desired result, try selecting Always refresh from server.


Clear the Office cache on Mac

Add-ins are often cached in Office on Mac for performance reasons. Normally, the cache is cleared by reloading the add-in. If more than one add-in exists in the same document, the process of automatically clearing the cache on reload might not be reliable.

You can clear the cache by using the personality menu of any task pane add-in.

  • Choose the personality menu. Then choose Clear Web Cache.


    You must run macOS version 10.13.6 or later to see the personality menu.
