SQL database instead an ESE engine in Exchange 2010 ???

Not for now...but this have been implemented successfully by the Exchange Team:

As most of you know, Exchange servers utilize the Extensible Storage Engine (ESE) database. As you have told us loud and clear, Exchange rocks from a performance, scalability, and availability standpoint on ESE and we've worked hard to make it so.

However, for some time (it has been a topic of discussion since the development days of Exchange 2003) there have been questions and rumors around replacing the ESE database with SQL Server.
Did the team consider using SQL Server for the next version of Exchange? - Absolutely!
Did it work and perform well? - Yes! Some very smart engineers did amazing work, and we had mailboxes up and running using a SQL Server database.
Did we ultimately decide to replace the ESE database with SQL Server for the next version of Exchange Server - No.

Why not! you ask - It was ultimately determined that the best way to ensure we could drive compelling innovation into Exchange for 2010 and beyond was to remain committed to ESE. Enhancements made to the ESE database for Exchange 2010 have yielded significant performance benefits, High Availability benefits and provided customers with further opportunities to lower their storage costs. As we march forward on a path of developing Exchange for both on-premises deployments and cloud services, there are a number of areas that you are looking to us to make further improvements and new feature investments in the product.

NEWS!!!! -- Critical vulnerability in Adobe Flash Player

A critical vulnerability exists in Adobe Flash Player and earlier versions for Windows, Macintosh, Linux and Solaris operating systems (Adobe Flash Player and earlier for Chrome users), Adobe Flash Player and earlier versions for Android, and the authplay.dll component that ships with Adobe Reader and Acrobat X (10.0.1) and earlier 10.x and 9.x versions for Windows and Macintosh operating systems.

This vulnerability (CVE-2011-0609) could cause a crash and potentially allow an attacker to take control of the affected system.

There are reports that this vulnerability is being exploited in the wild in targeted attacks via a Flash (.swf) file embedded in a Microsoft Excel (.xls) file delivered as an email attachment.

Adobe is not currently aware of attacks targeting Adobe Reader and Acrobat. Adobe Reader X Protected Mode mitigations would prevent an exploit of this kind from executing.

NEWS!!!!! ---Exchange 2010 SP1 Rollup 3 and BlackBerrys sending duplicate messages

If you have BES and Exchange 2010 SP1 RU2 hold on...do not install the RU3!!!!!!
From the EHLO blog :
We have received notification of an issue impacting some customers which have RIM BlackBerry devices connecting to an Exchange 2010 SP1 RU3 environment. At this stage we are actively working with RIM to identify the exact scenarios in which customers are reporting this issue in order to narrow down the root cause of the problem and identify a suitable resolution for it.
As a precautionary measure we have deactivated the download page for Exchange 2010 SP1 RU3 until we can identify the appropriate next steps.
If you are a customer seeing duplicate messages being delivered when an email is sent from a BlackBerry device and you have RU3 installed within your Exchange 2010 environment, our recommendation is to contact Microsoft Support for assistance in troubleshooting the issue you’re experiencing.
