I have a custom form that has been used for years with Outlook 2003. We have upgraded to Outlook 2007 (SP3), and are experiencing a problem with the Message field. When the form is completed and sent from one user to the next, the Message Field does not retain any of the contents (signature, custom message, etc.) that the author added. Other times, it will retain the information, but will "drop" the contents after the form has been Replied To or Forwarded several times. It is very intermittent. Please let me know if you have any thoughts on what could be causing this. The form design was not changed at all during the conversion from 2003 to 2007, and the problem never existed while using 2003. Thank you.
