Issues with Outlook Web and HubSpot Add In

Hello,

I’m experiencing a persistent login issue with the HubSpot Sales Add-in while using Outlook on the web via Firefox.

The Issue: I can successfully complete the entire login cycle (entering credentials and 2FA), but the add-in does not recognize the session. It immediately reverts to the “Log In” screen, creating an infinite loop where it never actually registers that I am authenticated.

Environment:

  • Browser: Firefox (Latest version)
  • Platform: Outlook Web Access (OWA)
  • Troubleshooting done: I’ve attempted the login cycle multiple times with the same result.
