Recently I migrated one 2003 exchange organization to MS Exchange 2007 and updated with rollup 7. 30 % of our mailboxes are pop3 mailboxes becouse these messages are getting downloaded to another branch mail server(MS Exchange 2003 with pop3 fetching from main exchange 2007 server usig exchange pop3 software. All the things are working smoothly except am getting double read receipts from the users working in branch. I checked the headers of read receipt and I come to know that the first read recipt is generating by exchange 2007 while the message getting downloaded and the second read receipt is generaed by the client side itself(by outlook user).
While googling I got this technet article
Will apreciate if u can suggest a solution for disabling this feature of exchange 2007.
