Hello We're running Exchange 2007 SP2 / Outlook 2007 clients. A business unit wants to start sending out comms to a few internal / external users and be sure they are delivered. They have been asking about the Read Reciept and Delivery Reciept functions within Outlook. I'm not entirely sure myself, as far as I understand it Read recpt - shows that the recipient has opened the message Delivery recpt - shows that the message has been delivered to (not sure if it's mailbox, mailbox store, or mailbox server) a) Does anyone know the answer to what Delivery Recpt actually means? And how does this work with external mail systems? b) How do Read Recpts actually work? c) Will Read Recpts work internally only? How about if we sent the message to an external user?

Hi, Delivery reciept will be created by your mail server when the mail is delivered to the remote mail server. Read reciept can be delivered when the remote user opens the mail - but this might be disallowed by the remote server or the user can select not to send a read reciept. Leif

The detail information about Delivery status notification, please follow the link http://www.ietf.org/rfc/rfc1891.txt Also look at the thread below that had similar discussion please http://social.technet.microsoft.com/forums/en-us/exchangesvrgeneral/thread/8469887D-5877-4904-B9BA-731D3D216155 Regards, Pushkal MishrA

That's true only if the other server doesn't send DSNs. Otherwise it's the last SMTP server (the one that delivers the message to the mailbox) to touch the message, or the last SMTP server that offers to send DSNs, that sends the delivery receipt. >Read reciept can be delivered when the remote user opens the mail - but this might be disallowed by the remote server or the user can select not to send a read reciept. Yep. There's no guaranty that a Read Receipt will be sent (or if it's sent, that it will be received). If you want to keep track of who's read your stuff, put it on a web site that requires authentication and enclose a link to the page in the e-mail. Then record the user-id for each page view. --- Rich Matheisen MCSE+I, Exchange MVP --- Rich Matheisen MCSE+I, Exchange MVP
