✅ Steps to Resolve the Issue:

1. Enable Guest Invitation in Azure AD

Ensure that guest invitations are allowed in Azure Active Directory:

  • Go to Azure Active Directory > Users > User settings
  • Under External users, make sure:
    • “Users can invite guests” is set to Yes
    • Optionally, restrict this to specific roles or users if needed

2. Check Microsoft Teams Guest Access Settings

Verify that guest access is enabled in Teams:

  • Go to Microsoft Teams Admin Center > Org-wide settings > Guest access
  • Ensure Guest access is turned on
  • Confirm that features like messaging, calling, and meeting participation are enabled for guests

3. Review Group Creation and Membership Settings

Ensure that Team owners (like User1) have permission to add guests:

  • Go to Microsoft 365 Groups settings in Azure AD
  • Confirm that group owners can add guests to their groups

4. Check Conditional Access or Compliance Policies

Make sure there are no Conditional Access or Information Barrier policies blocking guest access.
