Unread messages are marked as "read" when Exchange Server 2007 processes the EXAMINE command

Consider the following scenario:

• You use an application to connect to a mailbox through the IMAP4 protocol.
• You use the Examine command to access folders.

In this scenario, the mailbox is accessed in read-only mode and changes to the state of the inbox cannot be made. Therefore, the unread messages that are synchronized to the application are still marked as �unread." However, the synchronized messages are marked as �read� although the messages were not read if you use the application to connect to a mailbox that is located on a Microsoft Exchange Server 2007 server.

This problem occurs because Exchange Server 2007 sets a wrong flag for messages when it processes the EXAMINE command.

To resolve this problem, install the following update rollup:
