Hi @Camile Fuerte
The policy "Direct Routing" is currently assigned to one or more users. You must assign a different policy to those users before you can delete this policy.
Based on the error message, you need to find out who is assigned to this policy and change their policy to a different policy before you can delete it.
For more information about using PowerShell to manage call routing policies, refer to:
Set-CsOnlineVoiceRoutingPolicy. and Grant-CsOnlineVoiceRoutingPolicy.
Hope this helps! Moreover, if the above is not your scenario or I have misunderstood anything, please correct me and provide us with detailed information about the issue including the screenshot so that we can better understand to further assist you.
