title: [Azure Policy]Apply tag and add the account info
body: <p>When creating a resource group with Azure Policy, I would like to force account information such as user ID and email address as tags.</p>
  
  <p><a href="https://docs.microsoft.com/en-us/azure/governance/policy/samples/apply-tag-default-value" rel="noreferrer">Sample-Apply tag and its default value</a></p>
  
  <p>As a result of referring to, it was possible to tag a fixed word, but I do not know how to obtain the aforementioned account information dynamically.</p>
  
  <p>If you know anyone, please teach me how.</p>
  
  <p>Thank you.</p>
