Breaking News from IT

IT emailed everyone the following:

IT will be decommissioning a legacy Exchange server from a previous configuration on Wednesday, 3/11/09 at 5:00pm. This change will not affect any users of our existing Exchange environment since there are no users presently hosted on this server. If you have any questions or concerns about this change, please contact the Helpdesk.

My question is: If this change will not affect any users, why are you emailing me about it over a month in advance?
