This book is also not a preparation guide for Exam 70-662: TS: Microsoft Exchange Server 2010, Configuring, or Exam 70-663: Pro: Designing and Deploying Messaging Solutions with Microsoft Exchange Server 2010, even though when you apply the knowledge and experience covered in this book, it will help you to pass these exams.
In SP1, this redirection is no longer silent. When your Exchange 2007 user logs in via webmail.wardvissers.nl, they are presented with this screen:
The text reads:
A temporary change has occurred that requires you to connect to a different server. To connect, click the button below. For security reasons, you’ll be asked to enter your user name and password again.
Sure enough, when you click Connect, you are redirected to legacy.wardvissers.nl, where you have to re-enter your user information.
Thankfully, the same sort of thing doesn’t seem to happen with Outlook Anywhere or ActiveSync clients.
I checked the LegacyRedirectType value on my 2010 SP1 CAS boxes and they are all still set to Silent. The issue occurs because the OWA virtual directory value for LegacyRedirectType is being ignored. This is an extraordinarily unfortunate thing to have been introduced with SP1. If you have a mixed Exchange 2007/2010 environment, I suggest you wait until the rollup 2 is out before deploying SP1.
Update 15 December 2010
Update 2 for Exchange 2010 and the fix is there described 2458419 "A temporary change has occurred that requires you to connect to a different server" error message when Exchange Server 2007 mailbox users try to access their mailboxes by using an Exchange Server 2010 Client Access server
You can download the rollup HERE
For Exchange 2007 you had PFDAVAdmin to set rights on the Public Folder store.
For Exchange 2010 (RTM & SP1) you have the tool ExFolder to set rights on the public Folder store.
But the Exchange Team did a great job to add Public Folder Rights to the Public Folder Management Console.
When you right click on the a public folder you can set permission on two ways.
1. Right click on the public folder and choose Manage Settings
I give my self Owner rights for this little demo.
2. Select Properties from the public folder and then select the Permissions tab. 
Microsoft released some days ago Forefront TMG Update 1:
SafeSearch Enforcement. Forefront TMG can enforce blocking adult text, images and videos from search results by popular search engines. SafeSearch can be enforced on specific groups or to the entire organization.
Including non-primary URL filtering categorizations. Forefront TMG uses an algorithm to select a URL’s “primary” category from among up to four categorizations provided by Microsoft Reputation Services (MRS). In Update 1 you can control access to sites that match any of the non-primary categorizations provided by MRS. For example, a URL with a primary categorization of News can now match a rule by any of its non-primary categorizations (such as Web Mail).
Support for Exchange 2010 SP1
Bug fixes and various other improvements. For details, see http://go.microsoft.com/fwlink/?LinkId=201151.
Last Friday I passed the 70-663 Designing and Deploying Messaging Solutions with Microsoft Exchange Server 2010 Exam with 981 points.
So I am very pleased with it. Last month’s I’m working a lot with Exchange 2010. I love the product. Last Friday evening I updated a customer DAG cluster to SP1. Next moth starting moving the 2000 mailboxes from Exchange 2007 tot Exchange 2010.
Some day’s ago Microsoft Releases Exchange 2010 SP1. When you install Exchange 2010 SP1 you need to install some hotfixes. The Exchange Team have made a nice over view witch hotfixes you need for the OS.

Some of the hotfixes would have been rolled up in a Windows update or service pack. Given that the Exchange team released SP1 earlier than what was planned and announced earlier, it did not align with some of the work with the Windows platform. As a result, some hotfixes are available from MSDN/Connect, and some require that you request them online using the links in the corresponding KBs. All these updates may become available on the Download Center, and also through Windows Update.
These hotfixes have been tested extensively as part of Exchange 2010 SP1 deployments within Microsoft and by our TAP customers. They are fully supported by Microsoft.
The TechNet article Exchange 2010 Prerequisites is updated with the hotfixes and install the prerequisites required for your server version (the hotfixes are linked to in the above table).
You can use the Install the Windows Server 2008 SP2 operating system prerequisites on a Windows 2008 R2 server. Only you have to run the following powershell command: Import-Module ServerManager
Installed Exchange 2010 SP1 on a Windows 2008 R2 Server with problems. I feels that the MMC is faster. Tomorrow upgrading a DAG/NLB cluster to Exchange 2010 SP1.
Microsoft has released Exchange SP1 
.
So What’s New in Exchange SP1:
New Deployment Functionality
During an Exchange 2010 SP1 installation, you can now select a new option to install the required Windows roles and features for each selected Exchange 2010 SP1 server role. For more information, see New Deployment Functionality in Exchange 2010 SP1.
Exchange ActiveSync
In Exchange 2010 SP1, you can manage Exchange ActiveSync devices using the Exchange Control Panel (ECP). Administrators can perform the following tasks:
For every user, the administrator can perform the following tasks from the user’s property pages:
SMS Sync
SMS Sync is a new feature in Exchange ActiveSync that works with Windows Mobile 6.1 with the Outlook Mobile Update and with Windows Mobile 6.5. SMS Sync is the ability to synchronize messages between a mobile phone or device and an Exchange 2010 Inbox. When synchronizing a Windows Mobile phone with an Exchange 2010 mailbox, users can choose to synchronize their text messages in addition to their Inbox, Calendar, Contacts, Tasks, and Notes. When synchronizing text messages, users will be able to send and receive text messages from their Inbox. This feature is dependent on the user’s mobile phones or devices supporting this feature
Reset Virtual Directory
In Exchange 2010 SP1, you can use the new Reset Client Access Virtual Directory wizard to reset one or more Client Access server virtual directories. The new wizard makes it easier to reset a Client Access server virtual directory. One reason that you might want to reset a Client Access server virtual directory is to resolve an issue related to a damaged file on a virtual directory. In addition to resetting virtual directories, the wizard creates a log file that includes the settings for each virtual directory that you choose to reset. For more information, see Reset Client Access Virtual Directories.

MailTips is a one of the new features of Exchange Server 2010. When a user sends a message, MailTips gives the some status information of the recipient and that helps to reduces unnecessary and undeliverable e-mails, as well as reduce some embarrassing things done by senders. MailTips are hosted as an Exchange Web Services on the Client Access Server.
MailTips are work with the Scenarios given below.
Configuring MailTips
Gather Organization wide configuration MailTips settings.
Get-OrganizationConfig | fl *mailtips*
Enable or Disable MailTips.
You must use “Set-OrganizationConfig” CmdLet to enable or disable mailTips. Mailtips are enabled by default.
Set-OrganizationConfig -MailTipsAllTipsEnabled $true
Configure the large audience size for MailTips.
You must use “Set-OrganizationConfig” Cmdlet to configure large audience size. With a fresh Exchange Server 2010 installation it would be 25 by default. If we decrease it to 15, then Mailtip would be display to sender if sender add more than 15 recipients. See figure 3.
Set-OrganizationConfig -MailTipsLargeAudienceThreshold 15
Large Audience Threshold MailTip will display after adding more than 15 recipients . See figure 4.
Enable or disable the External Recipients MailTips
We have some embarrassing experiences of sending some internal information to external parties. However company doesn’t want to restrict sending emails to outside domains. With MailTips at least we can give a alert to the sender before click send button. See figure 5.
Set-OrganizationConfig –MailTipsExternalRecipientsTipsEnabled $True
External Recipients MailTips displays when trying to send to an external domains. See figure 6.
Enable or disable MailTips that rely on mailbox data
Mailbox based MailTips are rely on the mailbox data. There are two Mailbox based Mailtips, The Recipient Out of Office and Mailbox Full MailTips, rely on the mailbox data.
Set-OrganizationConfig -MailTipsMailboxSourcedTipsEnabled $true
The Recipient Out of Office. You can get to know if whether the recipient is out of the office before you send the email. See figure 8.
Mailbox Full. If recipient’s Mailbox is full, you can know that before sending the email. See figure 9.
Configure Group Metrics
MailTIps relies on Group Metrics data to provide information on the the size of distribution groups and dynamic distribution groups. Exchange server normally query a lot of LDAP requests to the Active Directory to get group membership information for each message.This could affect the the performance experienced by the users. To eliminate these issues Exchange server uses the Group Metric data. Group Metric data can be scheduled to run during office hours. You should use Set-MailboxServer CmdLet to configure Group metric Data. See figure 10.
Set-MailboxServer DAGEK10-01 GroupMetricsGenerationEnabled $true
Used this article as Source for my article.
When install a Exchange 2007 or Exchange 2010 Server on vSphere there are some settings that will increase de performance.
- Use de VMXNET 3 Adapter
- Use per Disk a SCSI Controller
- Store the Log & Database files on physical Lun on a SAN
- Use the LSI LOGIC SAS controller for Windows 2008 & 2008 R2
- Use the VMware Paravirtual SCSI (PVSCSI) Controller for Every physical Raw Device Mapping (RDM).
Another TIP. Exchange 2007 & Exchange 2010 needs a lots of Memory. When choosing the size for the OS partition, swap file need also al lot of space.
