You receive duplicate read receipts from a user who is using an IMAP4 client in an Exchange Server 2007 environment

Symptoms

Consider the following scenario:

On a Microsoft Exchange Server 2007 server, you run the Set-ImapSettings -SuppressReadReceipt $true cmdlet in Microsoft Exchange Management Shell, and then restart the Internet Message Access Protocol (IMAP4) service.

Note The Set-ImapSettings -SuppressReadReceipt $true cmdlet specifies that IMAP4 users who enable the Send read receipts for messages I send option in their IMAP4 clients only receive a read receipt when the recipient opens the message.
You send a user an email message and request a read receipt.
The user logs on to the mailbox by using an IMAP4 client, and then opens the email message.
You receive a read receipt.

In this scenario, you receive another read receipt when the user selects to send the read receipt.

This issue occurs because the SuppressReadReceipt�flag for IMAP4 messages is always set to False.

To resolve this issue, install the following update rollup:
