Sharing Office Add-ins using Shared File

The blog shows you how to share Office Add-ins using Shared File option instead of have to use Visual Studio everything when you want to use your Office Add-ins.

The one who are reading this should have already known following:

1. Create a Web Application in IIS Website.

2. Share a folder using Windows Explorer.

3. Installed Excel 2016.

You must first create an Office Add-ins

Create a Web Application in IIS Website.


Open your Office Add-ins solution then you should have 2 projects. Publish your Web project to IIS Web Application, for example, officeapp.


Open the. Double click the Manifest file in your project. I point my url to my Web Application, for example, http://localhost:8082/officeapp/addin/home/home.html.


Now in Visual Studio select Build -> Deploy Build.


You should now see a folder, for example, OfficeAddIn1Manifest under your Manifest project folder.

Copy all the files into the same folder where the home.html is located.

Share the folder with Change permission. Here I use officeapp.


If you open your Excel go to Insert Tab and click Store then you will not see SHARED FOLDER tab available.


Go to File -> Options  -> Trust Center -> Trust Center Setting… -> Trust Add-in Catalog. Put in the url, for example, \\WIN-6Q4CPR3O6CC\officeapp\AddIn\Home. Click  Add catalog and check Show in Menu checkbox. (Ignore the http there, it still does not work for me).


Click OK and restart your Excel. You should see SHARED FOLDER and the Office Add-in now when you click on the Insert Tab and select Store.
