Dear all
I have an issue with OWA and read confirmation: my users don't have the preview pane and when someone receives an internal email that has "request read receipt" , he clicks on link "send the receipt" then the message is updated to "read receipt has been sent" but no message is sent. If you close and re open the email, you can still confirm it as read.
The environment is Exchange 2013 CU8, but i tried on CU7 with same results, on another infrastructure.
Any suggestion is appreciated.
Best regards.
Germano
