Important This article contains information that shows you how to help lower security settings or how to turn off security features on a computer. You can make these changes to work around a specific problem. Before you make these changes, we recommend that you evaluate the risks that are associated with implementing this workaround in your particular environment. If you implement this workaround, take any appropriate additional steps to help protect your system.



SYMPTOMS
When you are running Microsoft Office Outlook 2007 on a Windows Vista-based computer, you cannot publish free/busy information from the Outlook 2007 Calendar to an FTP server. When you try to publish free/busy information to an FTP server, Outlook 2007 creates a .vrb file on the FTP server. However, the size of the .vfb file is 0 bytes. The file does not contain any free/busy information.

Additionally, if you perform a network trace of the FTP session, the following error message is logged:

425 Can't open data connection



CAUSE
This issue occurs if the Windows Firewall on the Windows Vista-based computer is preventing the FTP protocol from successfully making a connection to the FTP server.

We do not recommend this workaround but are providing this information so that you can implement this workaround at your own discretion. Use this workaround at your own risk.
