Consider the following scenario:
- You configure Integrated Windows authentication for the Outlook Web App (OWA) in a Microsoft Exchange Server 2010 environment.
- You open a new tab in Internet Explorer 7 or Internet Explorer 8.
- You connect to the OWA, and then close the Internet Explorer tab.
- You repeatedly open and close a new tab to connect to the OWA. For example, you open and close a new tab to connect to the OWA seven times.
This issue occurs because the Exchange server creates an asynchronous request that does not correctly close a connection.
Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the "Applies to" section.
