Update 4/11/11: Please note that the E2010 SP1 RU3 will be available via Microsoft Update on 4/24/11.

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.
