You notice that a calendar that you published to the Internet by using the Internet calendar publishing functionality in Microsoft Office Outlook 2007 has stopped being updated on the Internet. You also receive the following error message:When you visit any Web site that supports Windows Live ID, you cannot sign out because the Web site shows that you are not signed in.

On a Windows Vista-based computer, Windows Internet Explorer 7 may use two different storage locations for Internet cookies. One storage location is used when the Enable Protected Mode check box is selected. The other storage location is used when the Enable Protected Mode check box is cleared. Windows Live ID uses the cookies to save the sign-in state. The Internet calendar publishing functionality in Outlook uses Windows Live ID for authentication. The cookies that this functionality uses are stored in and retrieved from the same storage location that is used by Windows Internet Explorer 7 when the Enable Protected Mode check box is cleared.

When you sign in to a Windows Live ID Web site and save a username and password while the Enable Protected Mode check box is cleared, Windows Internet Explorer 7 writes a Windows Live ID cookie (Windows Live ID A). Outlook uses this cookie when the user publishes calendars to the Internet by using the Outlook Internet calendar publishing functionality.

If the cookie that Outlook uses contains a Windows Live ID cookie (Windows Live ID B) that differs from Windows Live ID A, Outlook is unable to publish the calendar. This behavior occurs because Windows Live ID B is not enabled to publish the calendar that is owned by Windows Live ID A. This condition is permanent because the saved Windows Live ID cookie is always used by Outlook. Additionally, the saved cookie is never deleted either by Outlook or by Windows Internet Explorer 7.
