Microsoft Outlook-Add-in-BillMaker

This Outlook add-in demonstrates how to implement three types of command buttons: a button with a drop-down menu (each of which launches a task pane), a button that launches a task pane, and a button that runs a function that uses no task pane UI. The app appears when you open an existing appointment or meeting and allows you to create and send invoices to clients with whom you've met. This sample currently runs only with the Outlook 2016 desktop client.

The Add a charge button contains a three-option drop-down menu that allows you to apply charges for three different tiers of customers. The Make an invoice button generates an invoice out of all of the saved charges, and the Clear changes button clears all charges for the current customer.


Configure the add-in

  1. Clone this repository.
  2. Run npm install from your local repository to install both npm and Bower dependencies.
  3. Run gulp serve-static from your local repository to start development server.
  4. Go to and sign in with your Microsoft Office 365 account.
  5. Click the gear icon for the Settings menu on the nav bar, and then choose Manage add-ins.
  6. Click the plus (+) icon, and then choose Add from a file.
  7. Browse to this repository folder and choose manifest.xml.
  8. Then complete the wizard (Next, Install, OK) to make the add-in available on your Office 365 account.
  9. Finally, you'll have to open the app in a browser and trust the certificate for localhost:8443. The add-in won't run if your computer doesn't trust it.

Run the add-in

  1. After installing the add-in, open the Outlook 2016 client desktop application.
  2. Choose a calendar meeting.
  3. You'll be able to add charges and make invoices for the person who created the meeting.
