title: Deleting emails from Office 365 Groups
body: <p>Does anyone know if it is possible to use EWs with C# or Powershell or any other option to delete emails from an Office 365 Group.</p>
  
  <p>We have a very heavily used group that frequently gets full.  At present we have to manually delete using Outlook which takes an age.</p>
  
  <p>Tried an Office 365 retention delete policy but it doesn't seem to want to delete the emails.</p>
  
  <p>Any one got any ideas?</p>
