Microsoft Exchange Server Implementation & configuration

Because of the complexity of Microsoft Exchange Server management and administration, many companies want to consolidate thousands of Exchange users on one server. As a deployment grows, its increasing number of servers can make administrative tasks such as adding, moving, and deleting users extremely time-consuming for Exchange administrators.
Administrators must use a combination of applications to administer and manage the Exchange environment, which makes administration of large implementations more difficult. Future versions of Exchange Server will simplify some of these management and administrative tasks and will enable administrators to perform all Exchange administrative tasks through one application. However, for now, Exchange Server's diversity of tasks and tools leads many companies to want to consolidate as many users as possible on each Exchange Server machine.

Microsoft has been using the Security Development Life cycle (SDL) across its product lines for several years now, and we've seen an across-the-board improvement in product security as a result. As a security practitioner, this situation makes me happy indeed, but as an Exchange Server administrator, I want functional improvements to the product as well. Given that Microsoft is already actively working on the next version of Exchange, I wanted to set down a few things I'd like to see in the Exchange Server of the future.

Keep in mind that for every feature we get, there are other features that don't make the cut. Even with the company's massive resources behind them, Microsoft's developers have constraints that prevent them from adding every desired feature while still meeting their schedules and deadlines. That said, here are a few items from my wish list for the next Exchange release.

Let's start with a relatively easy one: The next version of Exchange should include full support for Outlook Web Access' premium mode in Firefox and Safari. Multiple-browser support is an important check box for the education market (where you're likely to find more people using non-Microsoft Internet Explorer browsers), but it's also something that I would expect to see from the company that pioneered the commercial use of Asynchronous JavaScript and XML (Ajax) in Web applications--not to mention that Microsoft Office Communicator Web Access and all of IBM's Lotus products already fully support these browsers.

How about certificates? Microsoft Exchange Server has a Certificate Wizard that helps you get the right set of machine names and subject alternative names in your certificate requests. Now that the OCS and Exchange product lines are part of the same business unit within Microsoft, perhaps the two teams could collaborate to produce a single certificate tool that collects all the necessary parameters for certificate requests? Network security and Exchange administrators everywhere would greatly appreciate and benefit from such a feature.

I've heard many requests for running Exchange services on Windows Server Core, the bare bones install option with Windows Server 2008; the obstacle here is that the current version of Windows Power Shell won't run on Server Core. The Windows or Power Shell teams might address this problem on their own; personally, I'd rather they spent their engineering efforts on giving us complete support for running Exchange under Hyper-V.

Mimosa NearPoint for Microsoft Exchange Server 1.0

With an innovative approach to archiving Exchange data on the fly, Mimosa NearPoint for Microsoft Exchange Server 1.0 offers a robust solution for storing and maintaining corporate message data. Though you need some expertise and server capacity to set it up, once this solution is running, it largely succeeds at simplifying the lives of both administrators and end users.

We've all deleted or misplaced an important message in Exchange. Instead of having IT search through backup files, with NearPoint, users can search past messages (even deleted ones) using keywords and other criteria via the Quick Search option in Outlook. Matching results from the Mimosa archive are displayed, along with a message preview window, so you can find lost e-mails. An advanced search option presents more filter options and mimics Outlook's own search capabilities.

Better yet, NearPoint automatically moves user's e-mail attachments into its archive so that they are stored there instead of in user mailboxes. The admin tool let us define and tweak such rules with ease using criteria such as attachment size and message date. This ingenious approach essentially automates the all-too-common chore of users having to clean out mailboxes. We like the reporting available in the admin console, as well. There are about a half dozen reports here, including a useful size and usage report—a must to keep track of the growth and health of your Mimosa archive.

When it comes to installation, Mimosa ranks as one of the more challenging solutions that we've run up against. Setup requires a capable server (or two) with plenty of disk storage space. (One terabyte of disk space is recommended. RAID support is a virtual must for archiving.) Administrators will need to know their Exchange server infrastructure well and do capacity planning based on the number and size of user mailboxes.

Once Mimosa's MMC console is installed, it's exactly what busy IT administrators need to gain complete control over Exchange archiving. The console lets you perform both large and small tasks—like restoring an entire server, as well as individual mailboxes—with ease, along with support for scheduling jobs.

An additional potentially time-saving option in NearPoint allows designated "auditors" to search across multiple mailboxes to find relevant messages, which may be required for organizations meeting regulatory requirements or facing a legal discovery process. Behind the scenes, NearPoint admins can set policies for saving executive-level messages for a period of years, for example, to meet corporate standards. In accord with these policies, messages will be automatically saved or purged from the archive over time.

Virtualization of Microsoft Exchange Server

Microsoft Exchange Server is a product which is used for making the purpose of emailing faster. This software is designed to make the work more efficient. Since nowadays the e-mail pays a vital role in the business dealings, so many companies are going for the Microsoft Exchange Server which has made their work much easier and faster. Microsoft Exchange Server not only has increased the reliability but also provides the feature if adding servers for other applications and hence its utilization makes the workload much easier.

The main advantage of the Microsoft Exchange Server is that it is used for providing security enhancement to many software packages.

Harmful threats like viruses spam and hackers can be neutralized by the use of this server.

Hence it is much more reliable and provides the confidence to the customers and employees that their email system is well protected and full potential utilization of their system can be done with the help of this server.

• Going for the virtualization of Microsoft Exchange Server: -

i. This server provides a cost effective technique and hence providing a simpler business environment. The use and costs of e-mails can be managed and hence the complexities which are increasing day by day can be controlled by the use of M.E. server.

ii. Besides the helpful features like flexibility, increase availability, reduction in cost, disaster recovery simplifications, your hardware products can be tested and provided with a valid virtual solution. This is the technique used in the virtualization of this server.

iii. These services are provided by the two leading software companies - Microsoft Exchange Server 2007 and VMware (leading data storage enterprise).

• Advantages of virtualization of Microsoft Exchange Server: -

It helps in increasing the reliability of the email system and also improves the disaster tolerant system by providing efficient infrastructure.

i. By encapsulating the Exchange Servers into virtual machines, it helps in simplifying the recovery of data for the improvement in the Exchange infrastructure.

ii. The VMware Infrastructure plays an important role in protecting the servers. So it is even more powerful technique with virtual machine.

It helps in improving the performance by the information exchange.

i. With the introduction of 'New 64-bit architecture' in Microsoft Exchange Server 2007, the performance of the system has improved as much more RAM usage can be done with the better coordination with VMware virtual machine.

ii. Hence better access to the disk can be done and more memory can be used.

Protect Data with Exchange Server 2007

Lucid8 delivers next-generation automated disaster prevention, optimization, protection, and recovery solutions for Microsoft® Exchange. Today, Lucid8 has over six-thousand product implementations to customers worldwide ranging from SMEs to Fortune 100 companies worldwide whose businesses depend on Microsoft Exchange 5.5, 2000, 2003, and 2007.

Fear of loss compels us to protect ourselves, our cars, our homes, our families and our friends. Our concerns for potential loss encourage us to take precautions to help mitigate risks. This is why most of us exercise, take our cars into the shop when they make unexplained noises or motions, and buy insurance policies in case of other catastrophic losses. I seriously hope that no one’s life is in danger from his or her messaging system, but I am fairly certain that most companies would be wounded should a catastrophic problem occur within the Exchange environment.

Exchange Server 2007 is as self-healing as Exchange has ever been, but without a healthy hardware platform, drivers, Active Directory, DNS, network, and regular policy management, it can go belly-up faster than you can say cardiac arrest. To make matters even worse, many Exchange administrators are not current with the latest CPR techniques nor have they been practicing preventive maintenance on their Exchange databases in order to minimize unplanned downtime. In this white paper, you will learn the bare and necessary facts you should know to proactively maintain your Exchange Server 2007 environment.

How to Creating mail users in Exchange Server 2007

Mail users are actual accounts in your Active Directory, but their email does not reside within your Exchange environment; they use their own messaging system, Hotmail account, etc. This may sound a lot like a contact, but the difference is that a contact is an object that represents someone who neither has a mailbox in your Exchange environment nor an Active Directory account, whereas the mail user still has an Active Directory account.

To create a mail user in the Exchange Management Console, begin by navigating to the Mail User node under Recipient Configuration in the console tree. In the action pane, click the New Mail User link (Figure A) to start the New Mail User Wizard.

Navigate to the Mail User node:-

Exchange Server support

Beginning the New Mail User Wizard:-

Since you are creating a user within Active Directory, you first need to provide user account information on the User Information page of the wizard, as shown in Figure 3-35. Then, because the user will utilize an outside messaging system, you will need to provide his or her external email address, as shown in Figure 3-36.

Rollup 5 for Exchange Server 2007 SP1

This is a heads up that Rollup 5 for Exchange Server 2007 SP1 is in the final stages of getting released and should be out in a couple of days. The next step for the Exchange team will be to release the Update Rollup onto the Download Center and then publish it to Microsoft Update. Microsoft Update publishing will happen 2-3 weeks after the Download Center publishing, due to internal policies and processes. We will let you know when this happens.

Regarding the overall patching experience, we have addressed the issue of Exchange 2007 managed services might time out during certificate revocation checks. While we will have a full list of issues fixed when the Rollup releases, some of major issues are:
  • CDCR: Need an option to apply ELC policy to only the root instead of applying it recursively to root and all subfolders
  • CDCR: Add generatePublisherEvidence enabled="false" to Exchange Services Config Files
  • SCR does not copy logs in a disjoint namespace scenario
  • SCR cannot be enabled when DNS suffixes differ on source/target in disjoint namespace scenarios
  • Exchange 2007 CAS cannot copy the OAB from the OAB share on Windows Server 2008-based Exchange 2007 CCR clusters
  • Messages get stuck in outbox on Windows Mobile 6.1 devices When using CAS proxy
  • CDCR: MSI patching doesn't update logon.aspx if the file is modified by customer
