I’m getting an AADSTS50105 error when trying to sign in. What does it mean?

This error means your organization’s Microsoft administrator has not yet granted permission to use Let’s Copilot. To resolve this, your global admin needs to approve access in Microsoft Entra (formerly Azure AD).

Specifically, two approvals are required:

  1. SaaS Accelerator, as the management system for Let’s Copilot licenses 
  2. Let’s Copilot, as the application itself, including necessary permissions (e.g., message.send) 

Once both are approved, users in your organization will be able to sign in and start using Let’s Copilot.

If you’re unsure who your global admin is, reach out to your IT department.
