I have developed an Excel add-in using the official Office Add-in development toolkit in Visual Studio Code and deployed it via the Office 365 administrator method. The first version deployed correctly, but after updating the code to a new version, clients do not automatically load the latest code.

To force Excel Office Add-ins to refresh after an administrator deployment in Office 365, you can use the following methods:

  1. Refresh Admin-Managed Add-ins:
    • In Excel, select Home > Add-ins in the ribbon.
    • Click on More add-ins.
    • Go to the Admin Managed tab.
    • Select the Refresh button in the top right corner. This should make the add-in reappear and reload it.
  2. Forced Admin Refresh:
    • IT administrators can create a registry key to force a refresh of the add-ins. The registry key to create is:
      • Key: HKCU\Software\Microsoft\Office\16.0\WEF\TrustedCatalogs\ClearInstalledExtensions
      • Value: DWORD = 1

These methods should help ensure that users see the latest version of your add-in after deployment.
