Ok. Brief description of the company. I have an exchange server running windows server 2003 standard edition. I have about 40 computers on my network. One location has 2 computers running the same email account lets say dbts@mycompany.com. This just happen recently like a week ago or maybe 2 weeks that when someone at that location tries to enter a calendar entry, it just disappears. Now what we have thought was that when the person enters a entry its probably doing it offline and when the server does the send and receives to connect to the serve it disappears. if that is the problem does anyone know how to fix that? if there is another solution to this we would like to know. So far it hit two location that has 2 computers with the same email configuration.
