On a computer that is running Microsoft Exchange Server 2010, you create a recurring appointment or a recurring meeting and set several exceptions by using a Collaboration Data Objects (CDO) application. When you open the exceptions in Microsoft Office Outlook, the body text of the e-mail message is invisible. However, Office Outlook displays the message text correctly.
This problem occurs because the PR_RTF_COMPRESSED property of the exceptions is set as blank by the CDO application.
To resolve this problem, install Update Rollup 1 for Exchange Server 2010.
