New Features in Exchange 2007 SP3

In the month of June 2010 Microsoft announced the release of Exchange Server 2007 SP3 which is a good news for Exchange Administrators because it has come up with some major changes as compare to previous version. In this article we will see some of the new and improved features of Exchange Server 2007 SP3:

Recently I have seen an issue where one user is unable to view newly created user in Global Address list. The issue was limited to single user so asked to download OAB manually. Later user informed to us that he was not able to download OAB as per our instructions and getting error while trying the same.

Error:

“0x80070005 the offline address book could not be updated because you have exceeded the download limit set by your administrator"

Recently came across a scenario where hub transport server of an organization was being breached for open relaying leading to consequences like choking the mail flow in organization, blacklisting the organization domain

We tried lot of solution which included trying to trace down the spammer,

Finally we solved and rescued the server using following procedure (looks simple but at point of attack it really doesnt clicks so fast)

1. Select 'New Transport Rule'

2. Type a name and comment and press next

3. From the conditions window select 'From users inside or outside my organization' and 'Send to users inside or outside my organization' and from the details select the 'Inside' links and switch both to 'outside' then press next

4. From the 'Actions' window select the last action 'Delete the message without notifying anyone' and press next

5. If you have any exceptions you can configure it in the 'Exceptions' window ,If not just press next again

6. Press 'New' then 'finish

7. Please also run the following command from the Exchange Shell:

Get-ReceiveConnector "YourReceiveConnectorName" | Remove-ADPermission -User "NT AUTHORITY\ANONYMOUS LOGON" -ExtendedRights "ms-Exch-SMTP-Accept-Any-Recipient"

Change the "YourReceiveConnectorName" to match your Receive Connector Name and that should disable anonymous relaying.

Also if you want to check status of your domain/organization/server you can use following link:

Public Folder Replication, Moving the Mailboxes and Decommissioning the Legacy Exchange Server

In my last article you have seen the transition of Client Access Server. This article would be my final article on Transition from Exchange Server 2003 to Exchange Server 2010. In this article I will show the replication of Public Folder Database, Mailbox Movement and finally decomissioning of Exchange Server 2003.

 Transition to Client Access Server 2010 – Part3

So far we have covered the topic on basic overview of Transition from Exchange Server 2003 to Exchange Server 2010. Installation steps like how to deploy exchange server 2010 in an existing environment. In this article we are purely going to focus on Transition from Exchange 2003 Internet Side Configuration to Exchange Server 2010 CAS.

Here is the list of few CMDlets which are useful in day-2-day operations; it is not necessary to remember the entire CMDle alwayst, the command will prompt to fill the values of the required parameters as shown in below images

Microsoft Exchange Server High Availability Comparison

A lot has changed in the way Exchange Server makes its database and service available seamless to the end users.

Check out the three diagrams of Exchange 2003, 2007, and 2010 High Availability.

Exchange Server 2010 comes with many new features and improvements. High Availability and Transport Redundancy is most visible change or improvement as you like it. In Exchange Server 2010 there is a redundancy built-in to the routing of messages through the Exchange environment called “Shadow Redundancy”.

Before I could go ahead with the installation of Exchange Server 2010, I would like to let you know that scope of this article –
After going through this article you will have the basic knowledge about the installation of exchange server 2010 with co-existence of Exchange 2003, how to move mailboxes, public folder, OAB, creation of connector in Exchange server 2010 and finally we will decommission the exchange 2003 server from one organization.

This is purely a lab environment testing and this whole transition article is based on the scope of giving a base idea how to do a transition from Exchange 2003 to Exchange 2007.
