We have an Exchange (2010) mailbox that is automatically monitored by a windows service, this service connects to the mailbox periodically using Exchange Web Services 1.1 and imports the emails into SQL - it then deletes the messages from the mailbox.
This all works fine, however, if someone emails this address with a "Request Read Receipt" - exchange is firing a "This message was deleted without being read" message back to the sender - this is quite embarrassing (and misleading) - short of modifying our service to somehow "read" the message prior to deletion - is there any way to configure exchange (via powershell or whatever) to ignore requests for a read receipt?
