The Error:
Failed to Mount Public Folder database after a lossy failover because the current setting for AutoDataseBaseMountDial. You Must run Restore-StorageGroupCopy before you can mount the Database
 

Solution:
Restore-StorageGroupCopy won’t work because it is public folder database.

Setting a Vink by Do not Mount this Database at Startup.

En give the active clustered mailbox server a  reboot. Then Cluster service will show that the other node is going online. Then the public folder is back online. After every reboot you must start to check if the public folder online is?

When you have a new installation of Exchange 2010 Server and you want to move all mailboxes, including all hidden Mailboxen (Arbitration) from the default database store to a database that you created. Here is how i did it.

When you try to delete the default database you will get this message:

The Database is not empty, even though it does look empty if you do a get-mailbox for the specific database:

get-mailbox -Database "Mailbox Database 1905367170"

There is a switch that you should use if you want to see all mailboxes, even the “hidden” Arbitration mailboxes:

get-mailbox -Database "Mailbox Database 1905367170" –Arbitration

This gives a different result.

As you can se the database is n’t as empty as we first thought. To move these mailboxes to the new database you can easily pipe the result of the get-mailbox command and create new move requests for all Arbitration mailboxes:

get-mailbox -Database "Mailbox Database 1905367170" -Arbitration | New-MoveRequest –TargetDatabase "MailboxDatabase1"

What’s New in SP3 for Exchange 2007

Windows Server 2008 R2 Support

Exchange Server 2007 SP3 supports all Exchange 2007 roles on the Windows Server 2008 R2 operating system.

Windows 7 Support

Exchange 2007 SP3 supports the installation of the Exchange 2007 management tools on a computer that is running Windows 7. Additionally, Exchange 2007 SP3 provides support for the installation of the Exchange 2007 Management Tools together with the Exchange Server 2010 Management Tools on the same Windows 7-based computer.

Improved Password Reset Functionality

Exchange 2007 SP3 introduces password reset functionality for Internet Information Services (IIS) 7.

To enable the password reset feature

1. Log on to the Exchange server that is running the CAS role by using an account that has local administrator rights.

2. Start Registry Editor, and then locate the following registry subkey:

   HLKM\SYSTEM\CurrentControlSet\Services\MSExchange OWA

3. Create the following DWORD value if it does not already exist:

   Value name: ChangeExpiredPasswordEnabledValue type: REG_DWORDValue data: 1

4. Exit Registry Editor.

 Updated Search Functionality

Exchange 2007 SP3 includes updates to the Exchange Search (MSSearch) component. MSSearch provides support for creating full text indexes for Exchange stores. Exchange 2007 SP3 updates the MSSearch binary files to MSSearch 3.1.

Schema Changes

Exchange 2007 SP3 includes Active Directory schema changes for certain Unified Messaging (UM) mailbox attributes. For more information, see Active Directory Schema Changes (SP3).

Support for Right-to-Left Disclaimer Text

Exchange 2007 SP3 includes support for Right-to-Left text in e-mail message disclaimers in a right-to-left language, such as Arabic. In earlier versions of Exchange, when you use a transport rule to create a disclaimer in a right-to-left language on an Exchange 2007 Hub Transport server, the text appears incorrectly when you view it from Outlook 2007.

Exchange 2007 SP3 adds functionality to the transport rule setting to fully support right-to-left text in disclaimers.

One of the new features of Exchange 2010 is DAG Database Availability Group. The Customer were i work now wants Exchange 2010 in a dag cluster because they have a datacenter for failback.
Because i going to implement Exchange 2010 at the customer i created a test setup.

Configuration:

Server 1 – HYPERVDC-01
OS: Microsoft Windows 2008 R2 Standard x64
IP: 192.168.150.90
Roles: Active Directory / Hyper-V

Server 2 – CHEK10-01
OS: Microsoft Windows 2008 R2 Standard x64
IP: 192.168.150.91
Roles: Exchange 2010 HT / CAS

Server 3 – CHEK10-02
OS: Microsoft Windows 2008 R2 Standard x64
IP: 192.168.150.92
Roles: Exchange 2010 HT / CAS

Server 4 – DAGEK10-01
OS: Microsoft Windows 2008 R2 Enterprise x64

Server 5 – DAGEK10-02
OS: Microsoft Windows 2008 R2 Enterprise x64
IP: 192.168.150.94
Roles: Exchange 2010 MBX

Creating the DAG

Groupname: DAG01
Witness Server: CHKEK10-01 (Microsoft says use one of the CAS or Hub Servers. You cannot use a DAG Server! If you want use a non Exchange 2010 server you must at the Exchange Trusted Subsystem group at the local administrators group.
Witness Directory: C:\DAG01

Add a MB server to a DAG

Setting a IP address on a Database Availability Group

With the following command you can set the DAG Database Availability Group an IP address. Set-DatabaseAvailabilityGroup -Identity DAG01 -DatabaseAvailabilityGroupIpAddresses 192.168.150.96

The Exchange team has released Update Rollup 4 for Exchange Server 2010 RTM (KB 982639)

KB 982639 lists all the fixes included in this rollup. Here are some of the product improvements and critical bug fixes we’d like to call out starting with 5 improvements we made to prevent crashes in very unique scenarios.

• KB 980852 The RpcClientAccess process on an Exchange Server 2010 server crashes when you access a mailbox by using a MAPI application
• KB 979801 An error message is generated in Exchange Server 2010 when you use Exchange Troubleshooting Assistant
• KB 980364 The Exchange Transport service on an Exchange Server 2010 server crashes when a certain message is processed
• KB 980353 A MAPI application that is used to access Exchange Server 2010 mailboxes crashes when the application accesses an address book
• KB 979790 An IMAP4 client crashes when accessing an Exchange Server 2010 mailbox

We corrected a few replication issues some of you encountered.

• KB 980149 The Add-MailboxDatabaseCopy command fails when it is used to add a database copy to a Database Availability Group in an Exchange Server 2010 environment
• KB 981961 Event ID 4033 is logged and the Free/Busy replication from an Exchange Server 2003 server to an Exchange Server 2010 server fails
• KB 979921 You cannot replicate a public folder from one Microsoft Exchange Server 2010 server to another, and Event ID 3079 is logged on the target server

Important:
Microsoft Update does not detect Update rollups on Exchange Server 2010 Mailbox servers that are part of a database availability group (DAG).

When you want to use the Client Access Array function from Exchange 2010. You have to options.
1. Use the NLB function in Windows. Check this article that i blogged: Configuring NLB for Exchange 2010 for Cas load balancing.
2. When you have 2 physical load balancers in combination with a DAG cluster.

I haven’t any pre-Created CAS arrays in my hyper-v.local domain. But you would to check of there is any pre-created CAS Arrays. Run the command below. if you didn’t create a CAS Array before, you will get nothing .

Get-ClientAccessArray

Then you should create new Client Access Array. Run below Cmdlet in Exchange Management Console

New-ClientAccessArray –Name “CasArray1” –Fqdn casarray.hyper-v.local -Site “Default-First-Site-Name”


Now we have finished creating a CAS array. Then we must associate databases with this CAS Array.
Use below CMDLet to add mailbox database to CAS array. We can attach all mailbox databases at once as shown as shown  below

Get-MailboxDatabase | Set-MailboxDatabase -RPCClientAccessServer “casarray.hyper-v.local”

Exchange’s dependence on the Client Access Server (CAS) role has increased dramatically in Exchange 2010.  This is because, in Exchange 2010, on-network Outlook MAPI connectivity now connects to a mailbox through the CAS role via the RPC Client Access Service.  As a result, high availability of the CAS role is crucial since any failure of CAS could affect Outlook client connectivity.  For smaller implementations or those where the limitations of native Windows Network Load Balancing (NLB) are not a major problem

You need two or more Exchange 2010 servers (each with two NICs) with the CAS role installed have been deployed, you are ready to start configuring NLB to provide high availability and load balancing.  First, you must allocate a dedicated private IP address and create an associated A record in DNS for the NLB cluster. 

This IP address and name are what clients will connect to and against which the ClientAccessArray will be created.  In this blog post, I will use 192.168.150.95 and casarray.hyper-v.local
To simplify the management of your NLB cluster members, I recommend that you name each NIC’s network connection so that it is easy to understand what function the NIC serves.  For example, as depicted below, I have named the connections “LAN” (used for communication with clients and servers on the network) and “NLB” (used for internal NLB heartbeat).  This process should be repeated on all NLB cluster members.

IP configuration:
Server 1:
LAN:
IP: 192.168.150.90
Subnetmask: 255.255.255.0
Gateway: 192.168.150.254
DNS: 192.168.150.1

Server 2:
LAN:
IP: 192.168.150.91
Subnetmask: 255.255.255.0
Gateway: 192.168.150.254
DNS: 192.168.150.1

Configuring NLB – First Member

On each NLB cluster member, NLB must be installed.  With Windows 2008 R2, this can be completed simply by running the command “ServerManagerCmd -i NLB” via a command prompt.  Once NLB has been installed, launch the Network Load Balancing Manager to continue the configuration process.

To create your new cluster, you can right-click Network Load Balancing Clusters or simply click Cluster, New.  In the New Cluster wizard, enter the name of the first server in the NLB cluster (for example, CHEK10-01) and click Connect.  This will display the available NICs on the server, at which point the NLB NIC should be chosen before clicking Next.

Since this is the first member of the NLB cluster, you can leave the all of the Host Parameters at their default values, as depicted below.  Please note that the Priority value should be configured as 1 for the first member.

Next we must configure the IP address and subnet mask of the NLB cluster, which is the IP address for which we created a DNS A record at the very beginning of this process.  In this example, this would be 192.168.150.95 and 255.255.255.0, respectively.

For the Cluster Parameters, we want to enter the FQDN of the DNS A record we created at the very beginning of this process (casarray.hyper-v.local).  In addition, Unicast should be selected as the desired clustered operation mode.

I lieve the Port Rules how they are and end with Finish

Let the NLB cluster converge with its first member and you should eventually see the cluster report success.

Now you can proceed with adding your second cluster member.

Configuring NLB – Second/Subsequent Member

After the configuration of the NLB cluster itself and the first NLB cluster member has been completed, you are ready to add additional members.  Provided that NLB has been installed, you can simply right-click on your NLB cluster in the Network Load Balancing Manager and click Add Host To Cluster.

Enter the name of the second NLB cluster member, for example CHEK10-02, and click Connect.  Be sure to choose the NLB LAN NIC and click Next.

On the Host Parameters screen, ensure that the Priority is set to 2 (or as appropriate, depending on how many cluster members you have) and click Next.

Confirm that your port rules are accurate and, if they are, click Finish to add your second NLB cluster member.

Let the NLB cluster converge with the new member and, eventually, it should report success.

At this point, you have an NLB cluster with two members!

Next configure CASARRAY.
