System:  MS Exchange and Outlook 2007 (not sure which SP - probably SP4).

Scenario:

Original message was sent at 10:00 am EST so the message header (as seen in the message view) looks like this -

From:   orginalsender@whathaveyou.org

Sent:  Wednesday, 1 December, 10:00 am

To:  recipient@whathaveyou.org

Subject:  Some pretty important business

When the original message is viewed from the Sender's "Sent Items" folder, the message data look like that.

When the original message is viewed from the Recipient's "Inbox", the message data looks like that.

Problem:

When the recipient of the original message forwards that message to another recipient, the time in the Sent:  line of the original message changes.  The result looks like this:

From:   recipient@whathaveyou.org

Sent: Wednesday, 1 December, 10:05 am

To:  newrecipient@whathaveyou.org

Subject: FW: Some pretty important business

---------------Original Messsage---------------

From: orginalsender@whathaveyou.org

Sent: Wednesday, 1 December, 7:00 am      <===***Note the time has changed and appears that the original was sent 3 hours earlier than it was

To: recipient@whathaveyou.org

Subject: Some pretty important business

This is a significant problem.  It is alleged that the user (original sender) is "Making a False Statement" by manipulating the time-setting devices (Blackberry and Laptop) to create this result.  The user claims that he/she did not change time settings on any device.

All email parties, Original Sender, Recipient, and New Recipient are based on the East Coast and operate (normally) in the EST (GMT -0500).

The messages are routed through a server on the West Coast (GMT -0500).

Could this event be caused by the physical location of the server?  Has anyone experienced anything like this in the past?

This is a time-sensitive matter.  Any expertise would be greatly appreciated.  Thanks.
