Clear Microsoft Office Font Cache

-->

You can remove an add-in that you've previously sideloaded on Windows, Mac, or iOS by clearing 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 updated manifest. Doing so will allow Office to render the add-in as it's described by the updated manifest.

Click Clear Cache.; Restart Outlook. If that doesn't work, delete the Forms Cache Files. Locate the Forms folder.In Windows 7, 8 or Vista, its at C: Users username AppData Local Microsoft FORMS.

  1. The font cache is a file or set of files used by Windows to manage and display the fonts that are installed on your PC. Sometimes the font cache may become corrupted and cause fonts to be garbled or not appear properly. To fix the font cache corruption, you will need to delete the old font cache and restart the computer afterwards to rebuild a.
  2. A new Microsoft Edge DevTools window will open when the debugger attaches to your add-in. On the Network tab of the new window, select the Clear cache button. If completing these steps doesn't produce the desired result, you can also select the Always refresh from server button. Clear the Office cache on Mac.
  3. Two: the font cache is corrupted. As mentioned in the previous cause, the font styles are loaded by default when opening Microsoft Office utilities. In fact, they are stored as cache in a font folder on Windows.
  4. Or if the client has loaded the Microsoft Office shared library mso.dll, a D2D/DirectWrite RichEdit control will try to create an enhanced IProvideFontInfo object. The latter is a wrapper around the DirectWrite IDWriteFontFallback interface. In principle, this font binding handles all ISO scripts that Windows supports.

Additionally, to clear the Office cache on Windows 10 when the add-in is running in Microsoft Edge, you can use the Microsoft Edge DevTools.

Tip

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 F5 to reload the add-in.

Note

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 the Clear cache button.

  7. If completing these steps doesn't produce the desired result, you can also select the Always refresh from server button.

Clear the Office cache on Mac

Add-ins are often cached in Office for 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.

    Note

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

You can also clear the cache manually by deleting the contents of the ~/Library/Containers/com.Microsoft.OsfWebHost/Data/ folder.

Note

If that folder doesn't exist, check for the following folders and if found, delete the contents of the folder.

  • ~/Library/Containers/com.microsoft.{host}/Data/Library/Caches/ where {host} is the Office application (e.g., Excel)
  • ~/Library/Containers/com.microsoft.{host}/Data/Library/Application Support/Microsoft/Office/16.0/Wef/ where {host} is the Office application (e.g., Excel)
  • ~/Library/Containers/com.microsoft.Office365ServiceV2/Data/Caches/com.microsoft.Office365ServiceV2/
  • ~/Library/Containers/com.microsoft.Office365ServiceV2/Data/Library/Caches/com.microsoft.Office365ServiceV2/
