Side loading a Custom Add In disappears after I close the Windows Store from Outlook RRS feed

  • Question

  • Very perplexing

    I am developing an Outlook Add-In to open a pane from a button on the compose email window.

    I have loaded into a test account on outlook.com, and it works perfectly.

    When I go to side-load the add into Outlook Desktop (by loading the manifest XML directly by file), the system accepts it.

    However, when I close the Microsoft Add-In Store window, the add-in is not in the compose email, AND when I go manage my add-ins, the manifest I loaded is not there.

    The add-in is designed to fetch all icons and iFrame HTML from a web-server hosted on AWS.  

    A couple of notes

    1. The system does not reject my add-in.

    2. The add-in works perfectly on Outlook.com.

    3. I assume the add-in is being hard-deleted by the app for some reason?  If there is a way to troubleshoot these issues from Outlook, I would love to know.  This is my first outlook application (generally a mobile developer).

    4. The same issue happens for Outlook for Mac Desktop as it does Outlook for PC Desktop.

    Please help!

  • Hello Alex Holman,

    This forum(Outlook for developers) is for development issues related to Outlook Object Model and I think your issue is more related to Office-Addins developed by Office JavaScript API. According to the top stick thread

    Post Outlook Add-ins questions to StackOverflow. on this forum ,I would suggest you post your issue on StackOverflow and for current thread, I will move it to Off-Topic forum.

    Thanks for understanding,
