Update Rollup 3 has now been re-released.

Announcing the Re-release of Exchange 2010 Service Pack 1 Update Rollup 3 (V3)
On March 14th we posted an announcement to the EHLO blog about removing Update Rollup 3 for Exchange Server 2010 SP1 due to an issue related to Blackberry devices.

The Exchange Servicing team has fixed the reported issue with E2010 SP1 RU3 and is making available a new version of RU3 for our customers, version 14.01.289.007, (KB2529939). We strongly advise all customers install this newly released version of Microsoft Exchange Server 2010 SP1 Update Rollup 3 and to discard any prior version of RU3 (KB2492690) which you may have.

RU3 Installation Guidance:

• Customers with RU3 already installed within your Exchange environment
  It is not necessary for you to uninstall the existing RU3 within your environment. The new RU3 package can be installed over the top of the existing package installed on your servers.
  
  
• Customers with previous SP1 RUs installed within your Exchange environment
  You can simply install the new version of the RU3 package.

General RU Installation Guidance

Note for deployments that leverage Forefront Security for Exchange: For those of you running Forefront Security for Exchange perform these important steps from the command line in the Forefront directory before and after this rollup's installation. Without these steps, Exchange services for Information Store and Transport will not start back up. You will need to disable Forefront via "fscutility /disable" before installing the patch and then re-enable after the patch by running "fscutility /enable" to start it up again post installation.
We deeply regret the impact that these issues have had on you, our customers, and as always, we continue to identify ways to better serve your needs through our regular servicing releases.

Thank you .. after 8hrs of looking for a solution, I did what you suggested and it fixed the issue I had in OWA, EMC and EMS. Funny that disabling the redirect in IIS was not good enough.

I encountered the same issue and we found that a circular redirect had been populated into the web.config file on the Exchange Install Directory, ClientAccess, OWA

I removed the follwoing lines from the web.config

<system.webServer>
<httpRedirect enabled="true" />
</system.webServer>

After resetting the IIS services on the server we are no longer seeing the OWA errors. We did not have this issue prior to the application of SP1.
