Microsoft Teams Bot - OAuth Flow popup is working on mobile but getting errors on desktop app

12345abc 1 Reputation point


When I try to click the signin button to open the OAuth pop-up for my own microsoft teams messaging bot, I get the following error on both browser and desktop app: This action can't be performed since the app does not exist or has been uninstalled.

However, if I do it through the mobile app, it works fine.

I have added the start/callback pages to the validDomains of the app, and put callback page as part of redirect url. Although I'm using my own OAuth identity provider, I also added to validDomains.

May someone help investigate?

    Login pages don't render in iFrames, as a safeguard against clickjacking. Your authentication logic needs to use a method other than redirect. For example, use token-based or cookie-based authentication.
    It works fine in browser but MS Teams is implemented on I-frame, that is why you are getting this error.

    Please have a look into Microsoft Teams authentication flow for tabs flow.
