One of our uses sends ever mail with read receipt, she has enabled it in the oultook -> tools -> options -> Preference tab -> email options -> Tracking options.She often send mails to her colleagues with read receipts. She receives the read receipts with From populated. when she sends meeting reuqest, the From field is black from one of the user and another read receipt probably generated by the system.I check the internet headers from both these messages and found that the From: <> Return-Path: <>are blank.Has any one come across the with this situation?" Your message To: XXX; XXXX; XXX; XXXX Subject: Updated: XXXx XXXX Sent: 9/2/2009 2:51 PM was read on 9/2/2009 3:17 PM. ". The From field in this message is blank. swamy

Are the blank responses from ALL users, internal users, or external users? That might have something to do with it.Jim McBee - Blog - http://mostlyexchange.blogspot.com

Only from the internal users. As of now it is only from a single users. It happend only for meeting requests with read receipts.When a new message (Not meeting request) is composed with read receipt, the read receipt reaches with complete display name in the From Field.swamy

I am not sure about this. I have not seen this specific issue. What versions of Exchange and Outlook? Jim McBee - Blog - http://mostlyexchange.blogspot.com
