Base project for you to start writing your own Outlook web Add-On.
To get started, it has some basic routing + some basic queries to the Outlook API to list the attachments of the current email. You can also download them.
Well, first you gotta git clone, then cd inside it and :
npm inpm start
Then grab the manifest.xml and add it to your outlook add-ons.
First, login to your Outlook Web Client. Then, open one of your email and click and the three dots on the top-right of the email.
Click on "Download Add-Ons", then on the new window go to "My Add-Ons" ("Mes compléments" on the pic).
Once you're there, scroll down and click on "Add a custom add-on" > "Add from a file" and select the manifest.xml file.
If the project has correctly started using the previous commands (npm i and npm start), the add-on should be available to use.
By clicking on the three dots, you should see "Outlook-Web-AddOn" in the list. That's the add-on, so you just click on it to start it.
