Hello,

Is this Outlook, or Outlook express? As your question is in the web browsers section, it implies you are using a web browser to look at your Microsoft Outlook email on some exchange server. If that is the case, you may need to try and delete the message from Outlook itself on the main network (use the Outlook client to access your mailbox). You may also need to contact your network administrator, and see if they can help.

If this is not the case, please clarify more on what you are trying to do. Perhaps this is a webmail question.
