I have an Outlook 2003 SP2 installation on Windows XP SP2 that is receiving blank messages. I have set it to leave the messages on the server and determined that messages with attachments are causing the problem. They are not blank on the server. However, in Outlook they appear as blank 791 byte messages. I have made sure all updates are current and there is no antivirus installed on this system. I also disabled Outlook plug-ins. The messages are downloaded via POP3.
