ProxyAddress Update with PowerShell

Question

I want to update proxyaddress field with powershell but I get this message:
"Remove-AzureADUserExtension : Error occurred while executing SetUser
Code: Request_BadRequest
Message: Property 'onPremisesDistinguishedName' is read-only and cannot be set."

I have the sync between onprem AD e AZure AD, I want to reuse some nomore existing onprem AD users.
When existing, they were created and licensed to use Dynamics CRM. I cannot delete them in CRM so I want to reassign them (in CRM) to other esxisting onprem AD users.

Thanks in advance

Hello @Cunico Alessandro , both onPremisesDistinguishedName and proxyAddresses fields are read only. The later builds up from other field values. To know more about this please take a look to How the proxyAddresses attribute is populated in Azure AD so you can use in combination with Set-ADUser cmdlet.
