Best practices for using Exchange Online Archiving. By Michael Van Horenbeek, Techtarget. In part one, we looked at the value of having Exchange Online Archives in an organization and introduced you to how the archives work. Now we can take a look at some best practices for working with EOA. This list of best practices highlights some of the most important things you can do to make sure Exchange Online Archiving works to its full potential. Educating your end users is just as important as having sufficient bandwidth and taking your time with the rollout. These best practices are a result of several Exchange Online Archiving projects I've done and the feedback that came from each.

Provisioning archives. If you provision archives for users and plan to immediately populate the archive with historical data from their mailboxes, such as when configuring a Retention Policy to automatically move items created before a certain date to the archive, it's better not to build the archives in Office 3. Instead, create them on- premises, let the archives fill up and move them to Office 3. This will greatly improve the end user's experience. What happens if you don't do this?
It depends. For a small number of messages, there is no issue. But if Exchange is moving more messages to Office 3.
Outlook may become unresponsive. Dragging and dropping messages. The problem above is similar to the behavior of dragging and dropping messages from the on- premises mailbox to the online archive.
Outlook treats this action as what I like to call a "foreground" operation, which means Outlook immediately handles the action. Rollout EOA gradually.
Take your time with this deployment. There is no reason to rush the deployment as this will almost certainly have a negative effect on your end users' experience, and that's what really matters. Gradually introducing Exchange Online Archiving will give you time to collect feedback from your users and make changes to retention policies if needed. It's also a good test to see how the load on your support organization is after deploying the first archives.
Outlook connectivity. Although this isn't specific to Exchange Online Archiving, make sure you've installed the latest Outlook updates and patches, preferably for Outlook 2. Exchange Online Archiving. This will rule out any connectivity issues that could be caused by a missing an update.

By Michael Van Horenbeek, Techtarget. When Microsoft launched Exchange Server 2.
Personal Archives feature. Personal Archives are somewhat comparable to personal storage files, but hosted on the Exchange server in regular mailbox databases. The tradeoff to using Personal Archives is that you needed an online connection with the Exchange Server to access them. With the release of Exchange Server 2. Personal Archives had to be located in the same database as a user's primary mailbox.
While this might have been fine for some customers, many customers asked for more flexibility with storing the archive mailbox in alternate locations, like on another database or on another server. Exchange 2. 01. 0 SP 1 loosened the requirements and allowed the archives to be hosted on any database or server in the entire Exchange organization. Because of the benefits of a hybrid Exchange deployment, you can also store Personal Archives in Office 3. This option is referred to as Exchange Online Archives and is available as a separate SKU in Office 3. Exchange Online. The value of online archives.
Using Exchange Online Archives allows you to provide users with the functionality of an archive without necessarily having to maintain the infrastructure to support it. This puts you in the unique position of importing existing PST files into Exchange with little to no additional effort. Not only will you get rid of the burden of running PSTs in your environment, but Exchange Online Archives also can protect stored data. Another benefit - - and one of the main reasons why Exchange Online Archives is used - - is to offload data from the primary mailbox to the archives.
Because Exchange actually moves the item with no stubbing, the items and their overall footprint in the primary mailbox will decrease. This results in a smaller OST file when working in cached mode and an inherently snappier Outlook experience. This is especially true in environments that cannot yet take advantage of the new Outlook 2.
The slider allows you to specify how much data you want synchronized to your local OST file. In previous versions of Outlook, the entire primary mailbox is cached. But as good as this option seems, there are some specifics to keep in mind. When Exchange Online Archives will primarily be used to replace PST files, there will be some additional things to think about. How does Exchange Online Archives work? From a functionality standpoint, there is no difference in how Personal Archives and Exchange Online Archives work - - only the place they're stored is different.
This means the same retention policies and retention policy tags are used to determine what gets moved to the archive. Users can also drag and drop items to the archive, but this is strongly discouraged. To read the full article, go to: searchexchange. How can I access the Message Options and view the Internet headers in Outlook 2. The option to access Message Options in Outlook 2. Outlook 2. 01. 3 but there are alternative ways to access the dialog still and see the Internet headers of that message.
By opening the message first If you open the message in its own window (via a double click), then you can access the Message Options of the individual email in the following way: File- > Info- > button: Properties. By leaving the message closed. If you do not want to open the message first, but want to access the Message Options dialog directly from within the main Outlook window, then you can add the Message Options command to your Quick Access Toolbar; File- > Options Select the Quick Access Toolbar on the left. Set the “Choose commands from” dropdown list to; Commands Not in the Ribbon From the command list select; Message Options… Press the “Add > > ” button. Press OK. The option is now added to the Quick Access Toolbar at the top of your Outlook window and view the Internet headers of a message without needing to open it first.
Three Ways to Tighten OWA 2. Security. By Brian Posey, Search. Exchange. Tech. Target. While Exchange Server 2. Outlook Web App is never a bad idea. After all, OWA is exposed to the Internet as a Web application and, like any other Internet- facing Web app, is prone to attacks. Here are a few tweaks you can make to bolster OWA 2.
Eliminate the OWA private computer option. When users log into OWA 2. OWA 2. 01. 0 from a public computer or a private computer; many users skip this step. If users do not explicitly choose public or private, OWA assumes they are logging on from a public computer, and therefore uses a more secure profile. One way to improve OWA 2. This forces users into the more secure profile.
The easiest way to do so is to modify the logon. Note: Make sure you create a backup of this file before modifying it. The logon. aspx file is located in the c: \Program Files\Microsoft\Exchange Server\V1. Client. Access\Owa\Auth folder. To modify it, open the file in Notepad, then locate the following line of code: < td> < input id="rdo.
Prvt" value="4" onclick="clk. Sec()"> < /td> In this line of code, change the type from radio to hidden.
After doing so, save your changes. Next, open a command prompt window and enter the IISRESET command.
This resets both Internet Information Services (IIS) and OWA. The logon. aspx file will use your modified code after the reset. Users can no longer select the This is a Private Computer option. Another public/private computer option. In some cases it may actually be better to tighten the private computer security settings rather than abandon them altogether.
One way to do so is to change the automatic logout setting. Idle OWA sessions are disconnected after 1. You can modify this setting to make the time- out period much shorter. To read the full article, go to: This e- mail address is being protected from spambots.

With Exchange Server 2. Standard Edition or Enterprise Edition of Exchange Server to provide Web Access with a Frontend Server. That is quite different in comparison to Exchange 2. Server where you had to use Enterprise Edition to provide it. But before thinking of implementing a Frontend Server you should first consider your network infrastructure.
Do you have a DMZ (also known as perimeter network)? What kind of firewall(s) do you have?
Are you using an ISA Server 2. Especially using ISA Server 2. OWA Access over the ISA Server. For more information on ISA Server implementations please refer to the articles of Tom Shinder on this website. Preparing Exchange Server 2.
OWAYour Exchange Server 2. Backend Server and every user has HTTP as an allowed protocol. So you do not have to configure anything on your Backend Servers unless you want to prevent some of your users from accessing their mailbox using OWA. This can be done quite easily via Active Directory Users and Computers in the user properties. Figure 1: Enabling OWA for a user. The next step is installing and configuring your Frontend Server.
The easiest way to do this is to install it as a second Exchange Server in your organization. After that we should enable it to act as a Frontend Server. This can be generally done in the properties of your Exchange Server in Exchange System Manager. Figure 2: Configuring a Frontend Server.
If we choose this configuration the server changes from using the DAVEx process (to act as Backend Server) to the Ex. Prox process (acting as Frontend Server). The next step is to reboot the server to make the changes take effect. Then we should go through the following steps to make the Frontend Server a genuine Frontend by disabling all unnessecary services. On your Frontend Server you must have the following services running, every other service may be stopped without any trouble. HTTP- Service. Exchange System Attendant.
Exchange Routing Engine. You really do not need to run the Exchange Information Store, because there should not be any public folders or mailboxes on your Frontend Server. The best practice is to dismount and delete all databases on your server and then disable the Exchange Information Store Service. After you have successfully placed this server in the perimeter network (also known as DMZ) we now have to configure the appropriate ports on the firewall(s) to make our server run. On the intranet firewall (which connects the DMZ and the internal network) we have to open the following ports: For Exchange Communication. Port 8. 0 for HTTP.
Port 6. 91 for Link State Algorithm routing protocol For Active Directory communication. Port 3. 89 for LDAP (TCP and UDP). Port 3. 26. 8 for Global Catalog Server LDAP (TCP).
Port 8. 8 for Kerberos Authentication (TCP and UDP) Note: You should now configure the DSAccess service for perimeter networks on your Frontend Server. At first you should disable the check for available disk space at netlogon by using RPC. This can be done by changing the following registry key: HKEY_LOCAL_MACHINE\SYSTEM\Current. Control. Set\Services\MSExchange. DSAccess. Registry Value: Disable. Netlogon. Check. Value Type: REG_DWORDValue Data: 1.
In addition to this you should prevent DSAccess from pinging domain controllers. This can be done by creating the following key on your Frontend Server: HKEY_LOCAL_MACHINE\SYSTEM\Current. Control. Set\Services\MSExchange. DSAccess. Registry Value: Ldap.
Keep. Alive. Secs. Value Type: REG_DWORDValue Data: 0. Then you should configure your Exchange Frontend Server to connect to the DC and GC you want by editing the server properties in Exchange System Manager. For DNS communication: Port 5. DNS (TCP and UDP) For RPC communication: Port 1. RPC endpoint mapper (TCP) Ports 1.
RPC services Note: You can limit RPCs across the firewall by editing the registry of all your DCs. You should now change the registry setting of the following key: HKEY_LOCAL_MACHINE\System\Current. Control. Set\Services\NTDS\Parameters Registry Value: TCP/IP Port. Value Type: REG_DWORDValue Data: (available port)If you are using IPSec between Frontend- and Backend Servers you have to open: Port 5. IKE (UDP) Port 5. Authentication Header (AH) Port 5.
Encapsulation Protocol (ESP)If you want to provide high availability for your Frontend Server you could do this by configuring the Network Load Balancing Service (NBL) to act as a virtual cluster. NLB will then make sure that users connect to a running Frontend Server. Then every user connecting to OWA will connect to the virtual cluster and will then be redirected to one of your Frontend Server nodes. Implementing Security for Outlook Web Access. If you have successfully implemented your Exchange Front- End Server constellation for providing Outlook Web Access for your users, you may be concerned about security matters.
HTTP connectivity is not very secure and authentication information is always on the net as clear text. In addition to this, Outlook Web Access authentication is generally session based. This means if you do not logoff and close your browser you remain logged in. Especially in public web access areas where users are unable to close the browser window it becomes quite easy for other users to read and send emails in the name of a company user. Providing a secure HTTPS connection with an SSL server certificate is quite easy to implement. The most interesting decision is whether to use a web server certificate from an internal certificate authority or to buy one from a well- known trust center like Verisign or anyone else. This certificate must then be installed on your OWA server.
Figure 3: Installing a Web Server Certificate on an OWA Box. Now you can choose between a secure channel and a non- secure one. If you would like to require 1. But do not forget that some countries have laws that only allow 4. France). With a new feature in Exchange Server 2. OWA connections more secure. This feature is called “Form- based Authentication” which means you can configure a cookie timed- out session connection.
This can be quite easily implemented as shown in the following picture below. Figure 4: Enabling Form- based Authentication. After enabling this feature you have a default setting of 1. Then you must re- logon to get a new cookie and new OWA access.
Note: You can change the default timeout by changing the following registry setting: HKEY_LOCAL_MACHINE\SYSTEM\Current. Control. Set\Services\MSExchange. Web\OWARegistry Value: Public. Client. Timeout. Value Type: REG_DWORDValue Data: (possible setting decimal)and. Registry Value: Trusted. Client. Timeout. Value Type: REG_DWORDValue Data: (possible setting decimal)On both registry values the possible settings will vary from 1 – 4. After changing these settings you have to restart your W3.
SVC service. With the setting of compression you have the possibility of speeding up your connections, if you can make sure that your OWA clients are aware of the following requirements: Windows 2. Internet Explorer 6. November 2. 00. 2 or Netscape Navigator 6. Summary When establishing a secure way for users to access their mailboxes via the internet, you can implement Outlook Web Access but you have to make sure that everything in your OWA implementation is well planned so that you do not open more doors in your “Swiss Cheese” (your firewall) than needed. This article provides you with a deep drill- down view on how to secure your OWA implementation with the most secure state- of- the- art configuration today.
