Hi, We have a file management software and we need to build an outlook com Add-in. Here is a link to that - [login to view URL] We have the app built in react.js and we need to put it in outlook ([login to view URL]) . We may need to modify it as needed to support this. Please send me some projects you have done including publishing to the Microsoft outlook store. If not, please read the documentation and let me know if you can do it. We will determine the number of hours after.
