I have and Exchange 2003 server running on a Windows 2003 server.
I have several company directors involved in a very important project. Email sent from one of our lawyers to all the directors arrives on time for some of the directors, but it may late several hours for the others.
All the directors are using Windows XP, with all the patches and Outlook 2003. as usual late email puts a director in a disadvantaged or dangerous position if all the others answer and he/she does not.
I have a firewall and a filter appliance. We have checked the filter and there are no emails from the sender being held...and we know it arrived at some of the users inbox.
Any assistance is welcomed.
