There have been reports of an issue impacting some customers which have RIM BlackBerry devices connecting to Exchange 2010 SP1 with RU3. The product team are working with RIM to identify the exact scenarios, narrow down the root cause of the problem and identify a suitable resolution for it. During this time the download page for Update Rollup 3 has been disabled.

If you are seeing duplicate messages being delivered when an email is sent from a BlackBerry device and you have RU3 installed within your Exchange 2010 environment, contact Microsoft Support for assistance in troubleshooting the issue you’re experiencing.

It is recommended at this time that everyone hold off deploying RU3 until they have identified and resolved the issues. If you have already deployed RU3 and you are not seeing any issues within your environment, leave RU3 in place at this time.

The Exchange CXP team recently released Update Rollup 3 for Exchange Server 2007 SP3 and Exchange Server 2010 SP1 to the Download Center. Release via Microsoft Update will occur on March 22nd 2011.

These updates contain a number of customer reported and internally found issues since the release of RU2. Both updates resolve a number of issues, in particular for Exchange 2010 it resolves more than 40 issues.

For a detailed list of these issues, visit the following links:

• Update Rollup 3 for Exchange 2007 SP3
• Update Rollup 3 for Exchange 2010 SP1

Update Rollup 4 for Exchange Server 2007 SP3 and Exchange Server 2010 SP1  is currently scheduled to release in May 2011.

As always, those of you running Forefront, be sure you perform these important steps from the command line in the Forefront directory before and after this rollup's installation process. 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.

This one is slightly off topic, but I thought I would share it nonetheless. I recently came across a post about someone who upgraded through every version of Windows from 1.0 to 7.

What is truly impressive about this is that there is some 20 years of application compatibility to be witnessed. Here is the very impressive video:

The first thing I noticed when I watched this was that the author never installed Windows ME. I have since found his “FAQ”:

1) Why Didn't you Install ME?
Since Windows ME cannot be upgraded to 2000, I chose to install 2000 straight from 98 as it was chronologically the next release. I might do an "alternate history" version to see what going from 98 to ME to XP looks like.
2) Did Doom 2 and Monkey Island work in Windows 7?
Yes. Sorry I didn't point that out explicitly in the video.
3) Can you do the same thing with Mac OS?
I don't know enough about Mac OS to be able to say, and I would not be the best person to do that experiment as I have never been a Mac user.
4) Where are you from?
Scotland.

Last week the Windows Server team announced the Release to Manufacturing (RTM) of Windows Server 2008 R2 Service Pack 1 (SP1), along with Windows 7 SP1. On February 16, both will be available to current customers of the Windows Volume Licensing program, as well as subscribers to Microsoft Developer Network (MSDN) and TechNet. On February 22, both will be available to all customers through Windows Update and will also come preinstalled on new servers ordered.

"Is Exchange supported running on Windows Server 2008 R2 SP1?" The Exchange team have confirmed that the following versions of Exchange are supported to run on Windows 2008 R2 SP1 (the RTM version of SP1):

• Exchange 2010 SP1
• Exchange 2010 RTM
• Exchange 2007 SP3

There are a couple of things to note:

• Exchange 2007 was not supported to run on Windows 2008 R2 at all before Exchange 2007 SP3.
• Windows 2008 R2 SP1 includes all the hotfixes required to install Exchange 2010 SP1 so if you're installing Exchange 2010 SP1 on a server running Windows 2008 R2 SP1, you don't need to install these hotfixes separately.

The solution accelerators team has released a new Infrastructure Planning and Design (IPD) guide for Microsoft Exchange Server 2010 with SP1.

This guide provides actionable guidance for designing an Exchange Server 2010 infrastructure. The guide’s step-by-step process gives a straightforward explanation of the key steps required for a successful implementation. It can help you reduce planning time and costs, and ensure a successful rollout of Exchange Server 2010. The Exchange Server 2010 Guide includes the following content:

• Step 1: Define the Business and Technical Requirements
• Step 2: Define the Instances of Exchange Server 2010
• Step 3: Design the Mailbox Server Infrastructure
• Step 4: Design the Client Access Server Infrastructure
• Step 5: Design the Hub Transport Server Infrastructure
• Step 6: Design the Edge Transport Server Infrastructure
• Step 7: Design the Unified Messaging Server Infrastructure
• Step 8: Define the Active Directory Domain Services Requirements

I don’t often have much to say about mobile devices.. it is a frequently discussed topic amongst my friends and colleagues though and everyone generally has their own opinion.

I spent the last month testing a Windows Phone 7 device, The LG E900 to be exact. Before I share my thoughts with you, perhaps I’ll give you a little background. I use an iPhone, and I make no excuses for the fact that I love my iPhone. Before you start hurling abuse my way (this is a Microsoft centric blog after all, right?) I should mention that I have probably tried every Windows Mobile device out there, from the very first HP Ipaq’s, WM 2003 through to WM 6.5 but at the end of the day it was the iPhone that really changed the way I use a mobile device.

Windows Phone 7 – In short, I think its good.. certainly better than all previous Windows devices I have used. It’s responsive and quick and visually the interface is very slick. I like how it brings your contacts and Facebook together. What I did not like was how it requires a live ID to setup the phone and then automatically syncs those contacts to your phone as well.. no biggie, except you can’t disable this so if you are like me and don’t want your live ID contacts to sync to your phone, you need to ensure that your live ID is not your hotmail account. It does email and calendar well, but that is to be expected.

A few other things I don’t like.. no cut and paste (and yes, I know the early iPhones never had cut and paste either, but we are supposed to be progressing here..) There is no OCS/Lync client available for Windows Phone 7.. I honestly can’t believe that but I’ve been unable to find one.

Windows Phone 7 devices only support a subset of all Exchange ActiveSync mailbox policy settings so if you have Windows Phone 7 devices in your organization, they will experience synchronization problems if certain Exchange ActiveSync mailbox policy properties are configured. To allow Windows Phone 7 devices to synchronize with an Exchange mailbox, either set the AllowNonProvisionableDevices property to true or only configure the following Exchange ActiveSync mailbox policy properties:

• PasswordRequired
• MinPasswordLength
• IdleTimeoutFrequencyValue
• DeviceWipeThreshold
• AllowSimplePassword
• PasswordExpiration
• PasswordHistory
• DisableRemovableStorage
• DisableIrDA
• DisableDesktopSync
• BlockRemoteDesktop
• BlockInternetSharing

Another thing I found is that Microsoft appear to have dropped support for SMS sync with Exchange Server 2010.

In summary, I think Windows Phone 7 is a great step up from previous versions of Windows devices.. but I don’t think its quite there yet.. the app community is nowhere near as large that for the iPhone or even Android. I don’t see this as a enterprise device, it seems to be more consumer centric and does not really compete that well against the likes of the iPhone which is after all a consumer device. If you are currently making use of the enterprise features in WM 6.5 you may be disappointed with Windows Phone 7. I look forward to seeing further development in this space.

It’s been a long time coming.. Earlier this year it was announced that Exchange 2010 online archive support for Outlook 2007 would be coming. The good news is that it is finally here!

The December 2010 Cumulative Update for Office 2007 will allow users with Outlook 2007 to access their Exchange 2010 online archives. Organizations with Outlook 2007 deployed can now benefit from Exchange 2010 archiving and retention. There are a few BUT’s though.. the following functionality is not supported in Outlook 2007:

• Search across primary and archive mailboxes: When a user searches the primary mailbox, and selects All Mailbox Items, Outlook does not search the archive mailbox. Similarly, when the user searches the archive mailbox, the primary mailbox is not searched.
• Archive policies: In Outlook 2007, users can't use personal tags (also known as archive policies) to move items to the archive mailbox. Any default archive policies for the mailbox continue to be applied. Users can use Outlook Web App to see or apply archive policies. Archive policies are retention policy tags with the Move to Archive action. Organizations can use the Default Archive and Retention Policy, or apply custom retention policies to a mailbox. The policies can include a default policy tag (DPT) to move items from the primary mailbox to the archive mailbox, and personal tags which users can apply to messages or folders to move them to archive.

This is a slightly old interview with Microsoft’s Scott Schnoll where he talks about backup strategy in Exchange 2010. While some customers may find this to be an outrageous concept, he talks about how Exchange 2010 database replication can address most, if not all of the reasons you would traditionally backup Exchange using legacy backup technologies.

Every organisation has different requirements, the challenge is balancing these requirements while we embrace new technologies and evolve the way we think about things.

I previously posted about the Exchange Server Deployment Assistant. The Deployment Assistant asks you some questions about your particular Exchange environment and, based on your answers, it provides a checklist with instructions that are designed to help you deploy Exchange 2010 quickly and easily. Each step has a huge amount of valuable information to guide you through your deployment.

This great tool has recently been enhanced to include rich coexistence information for those interested in maintaining some users on-premises and some users hosted by Microsoft Office 365 for enterprises in the cloud. As of now, the available scenario is targeted solely at those organizations with a current Exchange 2003 on-premises implementation, but additional scenarios for supporting Exchange 2007 and Exchange 2010 will be coming soon.

I often talk about the Exchange 2010 Mailbox role calculator, I’m sure everyone uses it (everyone should be using it!) during the planning phases of any Exchange 2010 deployment. If you have no idea what I am talking about, click here now!

There is an area on the input tab where you define the number of processor cores that will have deployed for each mailbox server within your primary and secondary data centres, as well as, enter the SPECint2006 rate value for the system you have selected. The SPECint2006 rate value often causes some confusion so I thought I would write this post to try and clarify what to enter in the SPECint2006 rate value field.

In previous versions of the Exchange 2010 Mailbox role calculator (prior to 12.8) you had to enter the “Adjusted Megacycles / Core” which meant that you needed to normalise your server platform against the baseline platform -Intel Xeon x5470 3.33GHZ processors (2x4 core arrangement) and enter that value. To get to this value, you had to find your rate value and then use the following formula to calculate the “Adjusted Megacycles / Core” value:

In version 12.8, the field name has changed to “SPECint2006 Rate Value” which means you no longer need to normalise your server platform against the baseline platform and you merely enter the rate value.

To find the rate value, go here, click on “Results”, highlight “CPU2006” and then select “Search CPU2006 Results”. Under “Available Configurations”, select “SPECint2006 Rates” and click Go. Under “Simple Request”, enter the search criteria (e.g. Processor matches x5550) and find the server and processor you are planning to deploy and take note of the result value.

For example, let's say you are deploying a Dell PowerEdge M710 8-core server with Intel x5550 2.67GHz processors (2670 Hertz); the SPECint_rate2006 results value is 240, simply go back to the Exchange 2010 Mailbox role calculator and select “8” in the “Processor Cores / Server” field and enter “240” in “SPECint2006 Rate Value” field. Easy, huh?
