The "From" field in a meeting request displays the wrong user when two Exchange 2003 organizations are connected by using an SMTP connector

Consider the following scenario. Two Microsoft Exchange Server 2003 organizations (Org1 and Org2) are connected by using an SMTP connector. A user in Org1 sends a meeting request to a user in Org2. Then, the user in Org2 forwards the meeting request to a different user in Org1. However, when the different user in Org1 receives the meeting request, the From field shows that the meeting request was sent by the other user in Org1 instead of by the user in Org2.

This problem occurs if the following conditions are true:

• Exchange 2003 does not detect the correct data in the From field.
• Exchange 2003 does not use the correct data in From field.
