Hi,
We have just upgrade to Office 2013, form Office 2007.  and we appear to be having some issues with Read Receipts, if we ask for a read receipt on a mail, as soon as the mail is sent  we receive a not read receipt as shown below. 

"Your message

      To:   Ian Hart
      Subject:    RE: Consignment No.
      Sent: 24/04/2015 12:01

was deleted without being read on 24/04/2015 12:01."

I know that the mail are being received as I have sent a test mail from my work outlook 2013, to my own outlook.com and it was received fine although I did receive a not Read receipt on my work outlook.
if we resend a message with read receipts we do not get a not read receipt, could any one make any suggestions

1.) Mail Accounts are Microsoft Exchange  

I have looked into this further and the issue seams to be with the Read Receipts. 
I have sent an email with a Delivery Receipt and that delivers fine and I get a Receipt
I have sent a mail with only a read receipt and I get a not read receipt as shown in the post.
In not sure if the error is accruing because we are sending  to email accounts/ exchanges that have had the read receipt function disabled or if it is a problem full stop.

Best Regards 
Mark

Hi ,

I thought you would have to set the default mail delivery location in your outlook as your local PST file instead of exchange mailbox .So Please change it to exchange mailbox and check the read receipt is working as you expected by sending an new email along with read receipt enabled.

Hi Mark,

A read receipt informs you that your message has been opened. However, do not rely solely on these receipts. In Microsoft Outlook, the message recipient has the option to decline to send read receipts. There are other scenarios where read receipts are not sent, including if the recipient's e-mail program does not support read receipts.

I recommend you refer to the following article to troubleshoot the issue:
