Symptoms
Consider the following scenario:
-
You configure a read receipt to be automatically sent to the sender when a receiver receives the email message in a Microsoft Exchange Server 2010 environment.For example, you run the following commands to achieve this:
Set-MailboxMessageConfiguration -Identity receiver -ReadReceiptResponse AlwaysSend -PreviewMarkAsReadBehavior Delayed -PreviewMarkAsReadDelaytime 2After the receiver previews the email message for 2 seconds, the email message will be automatically marked as Read.
-
A sender uses Outlook Web App (OWA) to send an email message to the receiver. The sent email message requires a read receipt.
-
The receiver uses OWA to read the email message in a conversation view in the preview pane without expanding the conversation.
In this scenario, the email message is marked as Read. However, the read receipt is not sent to the sender unless the receiver marks the email message as Read by expanding the conversation and clicking on the unread email message.
Cause
This issue occurs because the Exchange server uses an incorrect logic when it sets the read state for email messages.
