A client does not display email message content in an Exchange Server 2007 SP3 RU1 environment

Consider the following scenario:

• You apply Update Rollup 1 (RU1) for Microsoft Exchange Server 2007 Service Pack 3 (SP3).
• By default, the Best body format option is set for POP3 and IMAP4 message retrieval on a Client Access server.
• The POP3 or IMAP4 client cannot display the HTML message format, and retrieves email messages from the Exchange Server 2007 server.

In this scenario, the POP3 or IMAP4 client does not display the message content.

This issue occurs because the POP3 or IMAP4 clients that use the Best body format�option retrieve only the native content that is stored on the Exchange Mailbox server. Therefore, the POP3 or IMAP4 clients no longer receive an additional text-only copy of the message. This means that if a client cannot display the HTML message format, the content of the email message cannot be displayed.

To work around this issue, select the HTML and alternative text option in the message retrieval settings. This configuration will apply to the POP3 and IMAP4 services on each Client Access server that provides service to users. Additionally, this configuration change takes effect after the affected services are restarted.
