Action required and recommendations
No action may be required if your tenant has not configured resource-specific Conditional Access policies for Teams Android devices. If your tenant has configured resource-specific Conditional Access policies and is experiencing sign-in issues:
- Ensure the following commonly blocked resources are included in the exclusion list:
- Microsoft 365 App Catalog Services (e8be65d6-d430-4289-a665-51bf2a194bda)
- Marketplace Extensions Runtime (08ff1ce2-4973-4b08-86a3-ebed13badc7f)
- Office Voice Front Door (446f6ff1-f129-4dd2-930e-c5c620fb4121)
- Review the interactive and non-interactive Microsoft Entra sign-in logs for the affected room resource account to identify any blocked sign-ins.
- Since the affected resource may vary, confirm the blocked resource and applicable Conditional Access policy in the sign-in logs before making changes to your policies.
