You install security update 931832 on a server that is running Microsoft Exchange Server 2003 Service Pack 2 (SP2). Additionally, you configure the Microsoft Office Outlook client in Microsoft Exchange Server mode. When you use Outlook to open an e-mail message that contains a PDF attachment from an external mail system, you receive the following error message:
There was an error opening this document. The file is damaged and could not be repaired.
Note This problem occurs only in Exchange 2003 SP2. You can open the PDF attachment as expected before security update 931832 is installed. Additionally, POP3 mail clients or IMAP4 mail clients may still synchronize messages and then open PDF attachments successfully after security update 931832 is installed.
