I have one Outlook 2013 user in an Exchange 2013 CU3 environment who has just recently received a couple of "Not Read" receipts from her own address. In each case the situation seemed to be similar: the sender sent a message to an external address with a PDF attached, with two internal users copied on the message, and read receipts enabled. Immediately after sending it she got a message like the one below:
Your message
To:
Subject: XXXXXXXXXXXXXXXX
Sent: Friday, June 20, 2014 9:21:06 AM (UTC-06:00) Central Time (US & Canada)
was deleted without being read on Friday, June 20, 2014 9:25:16 AM (UTC-06:00) Central Time (US & Canada).
What also seems odd to me is that Exchange and Outlook report the original message as being sent at 9:25, not 9:21 as this receipt states (this also happened in the other receipt).
Additionally, one of the internal users, who was copied on both emails, reported not receiving read receipt requests for either of those emails (haven't actually been able to confirm this yet), and indeed, though she read the emails, the sender didn't receive a receipt from her. The sender did receive read receipts from the external recipient and the other internal recipient though.
Does anyone have any idea what has happened with these messages? Is this just a known issue, a bug that can be fixed with an update, or is it some other error that can be corrected?
