I've been using MAC OS X Mountain Lion 10.8.5. How do I request a read receipt when sending e-mail with Outlook for Mac 2011?

share|improve this question

To make Mac OS X Mail request a read receipt for every message you send:

  1. Open Terminal and run the following command:

    defaults read UserHeaders
  2. If that command returns

    The domain/default pair of (, UserHeaders) does not exist

    run the following replacing Name with your name and email@address with your email address

    defaults write UserHeaders '{"Disposition-Notification-To" = "Name <email@address>"; }'

    For example, the complete line could read

    defaults write UserHeaders '{"Disposition-Notification-To" = "Heinz Tschabitscher <>"; }'"
  3. If the "defaults read" command above returns a line of values that starts with { and ends in }:

    1. Highlight the entire line. It might read something like {Bcc = ""; }, for example.

    2. Press Command-C.

    3. Type defaults write UserHeaders '

    4. Press Command-V.

    5. Type '.

    6. Insert "Disposition-Notification-To" = "Name <email@address>"; in front of the closing } character, replacing Name with your name and email@address with your email address.

      For example, the line might now read

      defaults write UserHeaders '{Bcc = ""; "Disposition-Notification-To" = "Heinz Tschabitscher <>"; }'
    7. Press Enter.

Welcome to Ask Different! Whilst this is useful information, the question is specifically regarding making Outlook request a read receipt, not – grgarside Aug 6 '14 at 19:11

Outlook:Mac doesn't have the read receipt feature.

And, frankly, you shouldn't use read receipts. Most mail clients can be set up to simply ignore read receipt requests. If the mail client isn't ignoring read receipt requests, then it gives the reader a message asking if the reader wants to send a read receipt; many people select no. The existence of a read receipt doesn't actually tell you whether your reader read your mail.

There may be specific reasons why Selahattin needs to request a read receipt. Why assume they are doing something wrong? "You shouldn't" isn't always true in this case. There's nothing dangerous, and there is have no reason to assume the Selahattin or anybody else is assuming anything about those read receipts. – samh Sep 5 '15 at 18:46

There is a new app that let you integrate read receipts in apple mail, both incoming and outgoing ones. Check ;) It does not work with Outlook though...
