Senders receive a message copy after they click "Reply to All" in Exchange ActiveSync

Symptoms

Microsoft Exchange ActiveSync users receive a copy of a message when they click Reply to All for a message in their mailbox.

Cause

This problem occurs because the client is receiving multiple PrimarySmtpAddress values in the response to the Settings command from the server that is running Exchange Server. When the user clicks Reply to All, the client does not detect the second PrimarySmtpAddress value within the recipient list. Therefore, the client includes the sender as a recipient.

The second PrimarySmtpAddress value is any SMTP address for the mailbox that is prefixed by an all-capitalized code value. The most common examples of such a value are the "SIP" address for Microsoft Lync and the "NOTES" address for Lotus Notes.

Resolution

To resolve this problem in Exchange Server 2013 or Exchange Server 2010, install one of the following updates:

Workaround

To work around this problem, manually change any existing address that is not the Primary address to all-lowercase characters.

Status

Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the "Applies to" section.
