  • Question

  • I want to grant an app to use my outlook calendar. Now I don't want that every time user should be authenticated to access that calander form that app or domain. so what values I need to store first time that I can access calendar next time without authorizing user.?

    so for now I am at this stage :

    I created app on https://apps.dev.microsoft.com

    I am able to authorize user and abel to get access token.

    Now need to know what to do so that next time no need to login and I can see my calendar. anyone can help here??

  • Hey,

    you can give your app some "special" permissions. These permissions are userless and have to be permitted by an administrator of your active direcory.

    The permission you need is named with something like "read calendar of all users". With this your app can read all calendars without authenticating as a user. 

    Here you can read the official guide for Authentication without a user context:
