Exchange public folders are widely used in on-premises Exchange environments. However, Microsoft® Exchange Online does not support customer usage scenarios of public folders. If you or your customers are using Exchange public folders, there are special considerations for migrating to Microsoft Office 365. This document outlines these considerations, discusses the most common public folder scenarios and how they are represented in Office 365 services. It also provides the information you need to decide whether Office 365 is a good match for you based on your current public folder usage.

Really Nice Overview What’s New in Exchange Server 2010
The Exchange Team created a really nice overview about What’s New in Exchange Server 2010.
Just Click on the Picture go to the Exchange Team site about What’s New in Exchange Server 2010.
DPM Error 30126 DPM could not find find a valid recovery point on disk Or ‘Replica Inconsistent’ showing against System State and Bare Metal Recovery on Protected Server
This error normally occurs due to one of the following two possible causes:
- Not enough disk space is available on the protected machine to store a backup of the system state files
- The Windows Server Backup feature is not installed on the protected machine (Windows 2008 or Windows 2008 R2)
Solution:
Simply install the Windows Server Backup feature on to the protected machine from Server Manager. Installation of this feature doesn’t normally require a reboot.
If the protected machine doesn’t have enough disk space to store a backup of the system state files (you’ll need 10-12Gb free on the system drive by default to store these files) you’ll need to create some space on the system drive, or add another disk to the machine and modify the PSDataSourceConfig.xml file to allow DPM to use the new location.
The PSDataSourceConfig.xml file is normally located at %SystemDrive%\Program Files\Microsoft Data Protection Manager\DPM\DataSources. Modify the <FilesToProtect> section of the xml file to point to the new drive added. Maybe that you may need to remove protection for the machine from the DPM 2010 console and then re-enable protection to get DPM to read the new location for backup files from the PSDataSourceConfig.xml file.
Exchange 2007 SP3 Update Rollup 5
Today the Exchange Team released Rollup 5 for Exchange Server 2007 Service Pack 3 (KB2602324). This update raises Exchange 2007 version number to 8.3.213.1.
Here’s the list of changes included in this rollup:
981820 New X-headers of a message item do not appear when the message item is retrieved by IMAP4 or by POP3 in an Exchange Server 2007 SP2 environment
2292150 A deleted hyperlink remains in the HTML source of an email message if you create the email message by using OWA in an Exchange Server 2007 environment
2411423 The Msftefd.exe process constantly consumes up to 100 percent of CPU resources when your mailbox language is set to German on an Exchange Server 2007 server
2450078 The sent time in an email message body is incorrect when you reply or forward the email message by using an EWS application in an Exchange Server 2007 environment
2451415 “There was a problem logging onto your mail server” error message when you use a POP3 client to access a mailbox in an Exchange Server 2007 SP3 environment
2536652 EdgeTransport.exe randomly stops responding on a Hub Transport server after you configure public folder replication in Exchange Server 2007
2536695 “Some items cannot be deleted” error message when you try to delete or modify an email message in a public folder in an Exchange Server 2007 environment
2536697 DBCS characters in a rule name are converted to question marks after you move a mailbox from Exchange Server 2003 to Exchange Server 2007
2537783 The EdgeTransport.exe process crashes occasionally after you install Update Rollup 2 for Exchange Server 2007 SP3
2538958 Extended Protection Warning Displayed in Exchange Management Console and Exchange Management Shell After Installing RU2 for Exchange 2007 SP3
2554575 Items accumulate in the MRM submission folder when managed folder assistant journal items in an Exchange Server 2007 environment
2556751 The EdgeTransport.exe process crashes when processing certain email messages on an Exchange Server 2007 Hub Transport server
2557304 The Store.exe process may consume excessive CPU resources and memory resources intermittently when a user opens a calendar item by using OWA in an Exchange Server 2007 SP3 environment
When running ForeFront Protection for Exchange, make sure you disable ForeFront before installing the rollup and re-enable it afterwards, otherwise the Information Store and Transport services may not start. You can disable ForeFront using fscutility /disable and enable it using the fscutility /enable command.
Note that update rollups are cumulative, i.e. they contain fixes released in earlier update rollups for the same product level (RTM, SPx). This means you don’t need to install previous update rollups during a fresh installation but can start with the latest rollup available right away.

Free Quest vWorkspace Desktop Optimizer
Quest vWorkspace Desktop Optimizer is a free tool to optimize the virtual desktop.
Blindly deploying entirely the same Windows desktop image that was used for the physical desktops is not the smartest thing to do. Running Windows in a VDI environment requires a decent amount of optimizing. This optimizing is nothing new. Quest has been optimizing SBC environments for over ten years now and many of things that we learned there (the hard way) apply equally to VDI environments.
Quest created a piece of software that contains our entire ‘optimizing knowledge’ called the Quest vWorkspace Desktop Optimizer and it is Free!
Although optimized for Quest vWorkspace environments, the Quest vWorkspace Desktop Optimizer will work just as well in Citrix XenDesktop or VMware View environments. You can download the Quest vWorkspace Desktop Optimizer HERE. Read HERE important information on how to use the Quest vWorkspace Desktop Optimizer.
Optimizing Windows 7 Images for use in VDI
One of our MCS deployment guys in the UK – Jonathan Bennett (you may know Jonathan as the author of the autoit tools and GImageX) has developed a tool for configuring Windows 7/Windows Vista/Server 2008 images for use in a VDI environment. The tool called VDI Optimizer outputs a VBScript (based on the selections you make in the GUI interface), which can then be used to apply performance and configuration settings to images that will be deployed via VDI platforms – this is particularly useful if you are using MDT 2010 for your image engineering process as the VBScript can bolted into the task sequence using a Run Command Line task.
You can make machine based selections for turning off services and functions that may not be required when the operating system is running in a VDI environment such as hibernation, system restore, and background defrag, as well as adjusting some user based settings such as visual effects, font smoothing and off-screen composition for Internet Explorer.
The beta of this tool is available from http://www.autoitscript.com/files/tools/VDIOptimizer.zip but please remember The tool is provided "AS IS" with no warranties, confers no rights, and is not supported by the authors or Microsoft Corporation.
The Deployment Guys released Deployment Mindmaps
"Why deployment is so hard?", “Where can I find all related information?” What else I need to consider?”
Those or similar questions are normal during my any projects. After getting the same questions again and again, The Deployment Guys decided to create a Mindmap with all common links you need to know if you in the deployment space.

Microsoft Exchange Server 2010 Performance on vSphere 5
A white paper has been published that examines how Microsoft Exchange Server 2010 performs on vSphere 5 in terms of scaling up (adding more virtual CPUs) and scaling out (adding more VMs). Having the choice to scale up or out while maintaining a positive user experience gives IT more flexibility to right-size system deployments and maximize total cost of ownership with respect to licensing and hardware purchases.
Testing shows the effectiveness of vSphere 5 to add compute power by scaling up Exchange Server VMs, in increments, from 2 to 12 virtual CPUs. This allowed the total number of very heavy Exchange users to increase from 2,000 to 12,000 while sendmail latency remained well within the range of acceptable user responsiveness. Processor utilization remained low, at about 15% of the total host processing capacity for 12,000 very heavy Exchange users.
Testing also shows that scaling out to eight Exchange Server VMs supports a workload of up to 16,000 very heavy users, with the load consuming only 32% of the ESXi host processing capacity.
Additional tests were undertaken to show the performance improvements of vMotion and Storage vMotion in vSphere 5. vMotion migration time for a 4-vCPU Exchange mailbox server VM showed a 34% reduction in vSphere 5 over vSphere 4.1. Storage vMotion migration time for a 350GB database VMDK showed an 11% reduction in vSphere 5 over vSphere 4.1.
