stop sending read receipts

Mail has no such feature. Are you asking about iMessages? Settings > Messages > Send Read Receipts > Off

There is no setting that will prevent this.

Sorry for the mix up. My crystal ball is having it's transmission replaced so I was unable to know in advance that you were using an exchange account. That was my bad. Anyways as KiltedTim posted and I hinted towards, Mail on an iOS device has no feature to control read reciepts.

Contact your Exchange server administrator.

I had the same problem before.

Outlook software cannot send read receipts. You should open your email account in the mail server and go to Settings to stop to send read receipts.

You're welcome

There is a work around this on the iPad (not sure about the phone). In mail click edit as if you were going to delete some of your mail. Touch the email you want to see and it shows you each opened one you check so you can read it. The "make sure" you cancel the edit (delete) or uncheck the email or it will delete it. You can read the email and it will not acknowledge you've even opened it on the Ipad or Outlook.

I solved the problem by logging into my exchange account in Outlook Web Access. Go to options and select mail options. From there I was able to turn off automatic read receipts.

I don't think the iPhone itself sent a read receipt and it was a server setting in exchange b

I tried this without success. I thought I had previously set both Outlook 2010 and Outlook Web Access to block read receipts. Then was shocked when someone showed me they had in fact received one from me. I noticed that the email in question was opened on my iphone (I have my work Exchange account on my phone).

Email from coworker with Read Receipt requested via Outlook

Opened and marked read in Outlook

No read receipt sent

Email #2 from different coworked with Read Receipt requested via Outlook

Opened on my iphone

Read receipt received by sender immediately

I don't think it's really that my phone is sending the read receipt, I think that when accessing the exchange account from my phone it's bypassing the options configured in Outlook and Web Access. Just my speculation.

Super annoying.

I logged into my Office 365 Outlook Web Access/Mail and disabled read receipts too, but believe another poster here commented that iOS devices are ignoring and/or by-passing the setting.

I'll have to see what it does for the Mail app on OS X.

But from what I've read in these forums related to the issue, if the mail.app doesn't support read receipts (which I realize is not a common standard), then why does it send a read receipt when you open/view an e-mail? That doesn't make any sense.

I've always disabled read receipts. I don't let email rule my day. Just because I opened an email doesn't mean I read it and should reply to it in a certain time frame. Your sense of urgency doesn't dictate a priority on my end.

In today's world, senders expect immediate responses, just like they do with text messages. That is ludicrous.

Thanks for letting me ramble. Sure wish there could be a setting or hack for OS X (at the terminal level) to disable this very annoying 'feature'.

It's bad, cause I don't want to confirm existence of mail account to spammers.

Yep - I agree - if I accidentally click on a 'spam' email - the sender gets a receipt - not good.

Anything been done about this yet?

It would be nice if Apple could figure out how to do this in iOS like other phone OS developers have.
