Outlook add-in wed service behaves differently in debug/IIS hosted RRS feed

  • Question

  • So in my outlook web add-in, I send the attachments meta data to the external web service which is under my control. And that service will use these meta data to get the binary content of the attachments via EWS managed api. Upon retrieval of the binary content the service will then sent those attachments to another domain for storage. That another domain is also under my control.

    So if run the external web service in debug mode, everything would be fine and the attachments will be sent through. However, if I use IIS to host the service, the attachments will not be sent through. And everything else seems to be fine. I then run the recipient domain in debug mode, I can see that when the service is run in IIS, the attachments receiver end point is never visited.

    So the service behaves differently when in debug mode and when run in IIS. I tried event viewer but cannot find anything useful. I have been scratching my heads last couple days.
