Internet Explorer freezes when you connect to the OWA several times in an Exchange Server 2010 environment

Symptoms

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.

In this scenario, Internet Explorer freezes. After some time, you receive a time-out error message.

This issue occurs because the Exchange server creates an asynchronous request that does not correctly close a connection.

To resolve this issue, install the following update rollup:
