Hi,
I'm having the following issue. We got an Exchange Server 2013 CU1 upgraded from the RTM version running on a Hyper-V VM under Windows Server 2012 (CAS and MB in one server).
The problem is as follows: When a user sends a mail message from Outlook/OWA, inmediatly receives a Read Receipt saying that the user deleted the message without being read. It started when we upgraded to CU1 and even we tried setting up a rule deleting the read receipts originating from our organisation, without results.
What could be generating the issue? Any help in this matter will be appreciated!
