Collection: Exchange Server 2003 (4)

1.    What are the considerations for obtaining a digital certificate for SSL on Exchange?
2.    Name a few 3rd-party CAs.
            Verisign, Entrust, GlobalSign, Comodo, Thawte, Geotrust

3.    What do you need to consider when using a client-type AV software on an Exchange server?
4.    What are the different clustering options in Exchange 2003? Which one would you choose and why.
       It is not sufficient to simply upgrade front-end servers to Exchange 2003 for users to get the new interface.
You must upgrade back-end servers to Exchange 2003 as well
Interface matrix
Ex2000 FE + Ex2000 BE = Ex2000 OWA
Ex2003 FE + Ex2000 BE = Ex2000 OWA
Ex2000 FE + Ex2003 BE = Not supported (AG protected)
Ex2003 FE + Ex2003 BE = Ex2003 OWA
Ability to Reply and Forward to Messages and Posts in Public Folders is only enabled when the client is using a front-end server. Forms-based authentication (FBA) is functional for deployments where the FE is Exchange 2003, but the mailbox is still on Exchange 2000. However, session timeouts are handled much better if the BE are also Exchange 2003

5.    Checking the Exchange Service Pack Level

Follow the instructions provided below:

1. Open Windows Explorer and go to the install folder of the Exchange server.

2. From the BIN directory, search for and select STORE.exe.

3. From to the Explorer menu, select File > Properties to view the properties of STORE.exe. Alternatively, you can right-click on STORE.exe to view the properties.

4.Select the Version tab to view the Exchange Service Pack Level of the Microsoft Exchange server.

6.    HOW TO Configure Connectors to Reject Messages from Specific

1. Click Start, point to Programs, point to Microsoft Exchange, and then click System Manager.
2. Expand the Administrative Groups object, expand the First Administrative Group object, expand the Routing Groups object, and then expand the routing group that you want to work with.
3. Expand the Connectors container, right-click the connector that you want to work with, and then click Properties.
4. Click the Delivery Restrictions tab.
5. Under By default, messages from everyone are, make sure that Accepted is selected.

101.      What is a Smart Host? Where would you configure it? 
Smarthosts are used to connect Exchange Server to an external (to the organization) messaging system. Typical use of a smarthost involves relaying outbound SMTP email to a non-Exchange SMTP host in perimeter networks; or to an ISP or hosted service provider that may offer functionality like mail relaying and spam and virus scanning

A smarthost is a common term for a server that accepts outbound mail and passes it on to the recipient.

A smart host is a type of mail relay server which allows an SMTP server to route e-mail to an intermediate mail server rather than directly to the recipient’s server. Often this smart host requires authentication from the sender to verify that the sender has privileges to have mail forwarded through the smart host. This is an important distinction from an open relay that will forward mail from the sender without authentication. Common authentication techniques inc Set Up Private Outbound DNS
Route mail to Outbound Services by setting up an external DNS server. For an overview of Private Outbound DNS concepts, see Alternate Option: Set up Private Outbound DNS.

Select the Start Menu -> Programs -> Microsoft Exchange -> System Manager.
Expand the top level -> Servers -> <Your Mail Server> -> Protocols -> SMTP.

Right-click Default SMTP Virtual Server & select Properties.

Click the Delivery Tab.

Click Advanced to go to the Advanced Delivery dialog box.

If you have a Smarthost set to point to Outbound Services for mail filtering, clear the Smarthost. The Private Outbound DNS will replace your Smarthost for routing.
Click Configure.

Click Add and enter the appropriate IP address for your system. Click OK.

This is a mail server. We can use this Server to send mails in Intranet as well as outside.

2.    What is a smart host?
This is the standard for sending mail. When Exchange needs to send mail to another domain it will look for the MX records of that domain and will attempt to contact the mail server directly.
Smart host-
In this case Exchange takes your outgoing mail and sends it to another mail server (which is called a “smart host”, hence the name). The smart host will deliver your mail to the other mail servers on your behalf. This is exactly what you do when you use Outlook Express to send mail using your ISP SMTP servers.

3.     An Exchange server is having bandwidth issues, explain how you would look at fixing the issue?

4.    What are the different Exchange 2003 versions?          

Standard Exchange version, Enterprise Exchange version and Small Business Server.

5.     What are the main differences between Exchange 5.5 and Exchange 2000/2003?
The primary differences are.
-Exchange 2000 does not have its own directory or directory service; it uses Active Directory instead.
-Exchange 2000 uses native components of Windows 2000 (namely, IIS and its SMTP, NNTP, W3SVC and other components, Kerberos and others) for many core functions.
-SMTP is now a full peer to RPC, and is it the default transport protocol between Exchange 2000 servers.
-Exchange 2000 supports Active/Active clustering and was recently certified for Windows 2000 Datacenter.
-Exchange 2000 scales much higher.
-It boasts conferencing services and instant messaging.

6.    What are the major network infrastructures for installing Exchange 2003?
Hardware Requirements
There are several factors that affect the hardware requirements for Exchange Server 2003: the number of users that will be accessing the server; the size and number of messages transferred on a daily basis (not to mention during peak usage periods); availability requirements; and so on. These factors will have a significant influence on the type of hardware you use for your deployment.
Component                           Minimum requirements
Processor                         Pentium 133
Operating system                         Windows 2000 Server + SP3

Collection:Exchange 2007 Edge Transport Server Role (2)

Exchange Address Rewrite in Exchange Server 2007

Exchange Address Rewrite in Exchange Server 2007 is already installed with the core messaging subsystem but is not enabled. You have to use the Exchange Management Shell to activate Exchange Address Rewrite.
One other new feature of Exchange Address Rewrite in Exchange Server 2007 is that you can enable this feature on a per user, SMTP domain and/or SMTP sub domain base and not for the whole Exchange 2003 Virtual SMTP Server as in Exchange Server 2003.
You configure Address Rewriting agents on the SMTP receive connector and send connector on a computer that has the Edge Transport server role installed.
Please note:The Exchange Server 2007 Address Rewrite Agent is only available on Edge Transport servers.

Collection: Exchange 2007 Mail Transport Query (2)

Troubleshooting Edge Transport Server Queues That Contain Mail Destined to a Hub Transport Server

This topic explains how to resolve issues where messages queue on a Microsoft Exchange Server 2007 Edge Transport server that are destined for delivery to an internal Exchange Hub Transport server. In the Queue Viewer, these messages display the error message 451 5.7.3 "Cannot achieve Exchange Server authentication".
This issue occurs when both Transport Layer Security (TLS) and Exchange Server Authentication are not configured on the default Receive connector of the receiving Exchange Hub Transport server. Therefore, you can resolve this issue by enabling TLS and Exchange Server Authentication on the default Receive connector.

Exchange Server 2007: Using Journaling Rules

Journaling: The traditional way...
In Exchange Server 2003, journaling took place directly in the mailbox store because there was no hub transport role.
In Exchange Server 2007 we can choose either to have the same option (allowing a Journal mailbox to receive all message traffic from a mailbox database) or to support a number of Mailbox databases. We can also create a separate mailbox database to store the mailbox which will receive the journaling.
In the following example, we are going to configure a mailbox database in Exchange Server 2007 to record all user messages that have been sent and received within the same database to be redirected to a specific mailbox.
To configure Journaling for a specific mailbox database, follow these steps:
