Microsoft Exchange 2010 Mailbox Auditing Theory And Practice

Exchange 2. 01. 3 Mail Flow (Part 2)If you would like to read the other parts in this article series please go to: Message Routing. The main purpose of the Transport service (present on all Mailbox servers) is to route messages to their final destination.

Routing decisions are made during message categorization, with the categorizer being the component of the Transport service that processes all incoming messages and determines what to do with them based on their destination. Because in Exchange 2. Mailbox servers host the Transport service, the routing process is now fully aware of Database Availability Groups . This way, if a Mailbox server belongs to a DAG, the primary mechanism for routing messages is closely aligned with the DAG because if the DAG spans multiple Active Directory .

The diagram below helps to understand some of these changes: Figure 2. Exchange 2. 01. 3 Transport Pipeline. The Transport service on a Mailbox server never communicates directly with a mailbox database. Instead, it communicates with the Mailbox Transport service which then communicates with the mailbox database on the local Mailbox server. When the Mailbox server is a member of a DAG, only the Mailbox Transport service on the Mailbox server that holds the active copy of the mailbox database accepts the message for the destination recipient; Remote Procedure Calls .

Instead, the Mailbox Transport service and the Transport service on different Mailbox servers communicate using SMTP; Instead of using one queue for all destinations in a remote AD site, Exchange 2. AD site, such as individual Send connectors; Linked connectors (a Receive connector linked to a Send connector) have been deprecated. As explained previously, when an e- mail is received by the Transport service it has to be categorized. First, recipient resolution is performed after which the ultimate destination can be determined. Now comes routing, where Exchange determines how to best reach that destination. As with previous versions of Exchange, the ultimate destination for a message is called a Routing Destination (note that the following also existed before): Mailbox database: any recipient with a mailbox in the Exchange organization has this as the routing destination. Because public folders are now also a type of mailbox, routing messages to public folder recipients is the same as routing messages to mailbox recipients; Connector: this can be a Send connector for SMTP messages, a Delivery Agent connector or a Foreign connector used as a routing destination for non- SMTP messages; Distribution Group expansion server: when a distribution group has a designated expansion server (no longer a Transport server but a Mailbox server in Exchange 2.

The Hidden Architecture of our Time: Why This Internet Worked How We Could Lose It and the Role Hackers Play. What we call the Internet, was not our first attempt at. This second article is all about theory and has lots of text which can be discouraging. However, it is important to understand some key features of how Exchange.

What is different in Exchange 2. Delivery Groups. Each routing destination has a collection of one or more transport servers (either an Exchange 2. Mailbox server or an Exchange 2. Hub Transport server) that are responsible for delivering messages to that routing destination, known as a delivery group.

If the routing destination is a mailbox database, the transport servers in the delivery group are the same version of Exchange as the mailbox database. If the routing destination is a connector or a distribution group expansion server, the delivery group may contain a mixture of Exchange 2. Mailbox servers and Exchange 2. Hub Transport servers. There are 5 types of delivery groups in Exchange 2.

In finance, an exchange rate (also known as a foreign-exchange rate, forex rate, ER, FX rate or Agio) between two currencies is the rate at which one currency will be. Download Game Dead Or Alive 4 Spartan.

When an external email comes in to our Exchange 2010 server and is destined for jobs@domain.com which is an email attached to a distribution group how can I send an.

Routable DAG: a collection of mailbox servers that belong to a DAG. The mailbox databases in the DAG are the routing destinations that are serviced by this delivery group. After the message arrives at the Transport service on a Mailbox server that belongs to the DAG, the Transport service routes the message to the Mailbox Transport service on the Mailbox server in the DAG that currently holds the active copy of the destination mailbox database.

The Mailbox Transport service on the destination Mailbox server then delivers the message to the local mailbox database. Although a DAG may contain Mailbox servers located in different AD sites, the DAG is the delivery group boundary; Mailbox delivery group: a collection of Exchange servers of the same version located in one AD site. The AD site is the delivery group boundary. The mailbox databases located on Exchange 2. Mailbox servers are serviced by the Exchange 2. Hub Transport servers located in the AD site; the mailbox databases located on Exchange 2.

Mailbox servers in an AD site that don't belong to a DAG are serviced by the Transport service on Exchange 2. Mailbox servers in the AD site. How the message is delivered to the mailbox database depends on version of Exchange: Exchange 2. Mailbox server in the destination AD site, the Transport service uses SMTP to transfer the message to the Mailbox Transport service which then delivers the message to the local mailbox database using RPC; Exchange 2.

Exchange 2. 01. 0 Hub Transport server in the destination AD site, the store driver on the Transport server uses RPC to write the message to the mailbox database; Connector source servers: a mixed collection of Exchange 2. Hub Transport servers or Exchange 2.

Mailbox servers scoped as the source server for a Send connector, a Delivery Agent connector or a Foreign connector. The connector is the routing destination that is serviced by this routing group. When a connector is scoped to a specific server, only that server is allowed to route messages to the destination defined by the connector.

This delivery group may contain Exchange 2. Hub Transport servers or Exchange 2. Mailbox servers located in different AD sites; AD site: in some circumstances, an AD site isn't the ultimate destination of a message, but the message must pass through an Exchange 2. Hub Transport server or Exchange 2.

Mailbox server in that site before it reaches its destination; Server list: a collection of one or more Exchange 2. Hub Transport servers or Exchange 2. Mailbox servers that are configured as distribution group expansion servers. The distribution group expansion server is the routing destination serviced by this delivery group.

Delivery group membership isn't mutually exclusive. For example, an Exchange 2. Mailbox server that is a member of a DAG can also be the source server of a scoped Send connector. This Mailbox server would belong to the routable DAG delivery group for mailbox databases in the DAG, and also a connector source server delivery group for the scoped Send connector. When a message is to be delivered to a remote delivery group, a routing path must be determined for the message.

Exchange 2. 01. 3 uses the same logic as Exchange 2. Calculate the least- cost routing path by adding the cost of the IP site links that must be traversed to reach the destination.

If the destination is a connector, the cost assigned to the address space is added to the cost to reach the selected connector. If multiple routing paths are possible, the routing path with the lowest aggregate cost is used; If more than one routing path has the same cost, the routing path with the least number of hops is used; If more than one routing path is still available, the name assigned to the AD sites before the destination is considered. The routing path where the AD site nearest the destination is lowest in alphanumeric order is used. If the site nearest the destination is the same for all routing paths being evaluated, an earlier site name is considered. Conclusion. This article was all about theory and more text than what I would prefer.. Photoshop 5 Serial Number. However, it is necessary to understand how Exchange 2. Routing Destination and Delivery Groups to route messages to their correct destination.

The third and final article of this series will be more interesting (I promise!) as we will be looking at how the Front End Transport and Mailbox Transport services route messages; we will trace an e- mail message through all the steps and processes discussed so far and finally we will have a look at Queues.

Using AD FS “Alternate Login ID” with Office 3. As Office 3. 65 adoption continues to grow and more organisations are starting to take advantage of identity federation. One of the most common issues I’ve seen over the last couple of years when helping my clients adopt Office 3.

UPN), s. AMAccount. Name (The user name typically used at logon) and the . There are many reasons for this and I won’t go into that in this post, but it is quite common to see one of the following scenarios: s.

AMAccount. Name = JSmith, UPN = JSmith@internal. Mail = John. Smith@domain. AMAccount. Name = ID1. UPN = ID1. 23. 45. Mail = John. Smith@domain. I’ve seen this scenario quite often when working with . In the past, the typical recommendation is to add the public domain to the UPN suffix list and change the UPN for each user to match their email address.

This causes much less confusion for end users as you won’t need to try and explain the different between their UPN and their email address even though they both appear to be the same.*Update: I’d like to call out that implementing “Alternate Login ID” with an Exchange Hybrid deployment is not a good idea. Microsoft has the following warning posted on the Tech.

Net wiki. The April 2. Windows Server 2.

R2 Update (KB 2. 91. Alternate Login ID” which will allow you to configure an alternate attribute to be used to identify a user object in Active Directory.

In other words, you can now use a different attribute, for example . As always, there are a few things to consider. In order for the authentication request to succeed, the attribute configured as the alternate login ID must satisfy the following requirements: The attribute must be indexed. The attribute must be in the global catalog. The attribute must be a well- formed SMTP address and conform to the UPN rules outlined here. The attribute must have a single value. The Canonical. Name attribute on the user object must be accessible to the service account that is used for AD FS.

The value of the alternate login ID attribute must be unique across all the forests that AD FS is configured to use when enabling this feature. The configuration process is really simple as well, for example let’s assume we already have AD FS 3. Office 3. 65. My test environment is configured as follows: Internal AD domain name: lab.

NOT configured in Office 3. Public (SMTP) domain name: o. This domain is also configured in Office 3. AMAccount. Name = ID1. UPN = ID1. 23. 45. Mail = John. Smith@o.

We would like to allow our users to log in using their email addresses (. This can be done via the “proxy. Addresses” attribute of the user account: Once the user has been synchronised to Azure AD and assigned the relevant licenses in Office 3. To configure AD FS, the first thing to do is install the April 2. Windows Server 2. R2 Update (KB 2. 91.

Windows Update: Warning: There is a known issue with the April 2. Windows Server 2. R2 Update (KB 2. 91. Windows Server Update Services. Be sure to read KB 2. As always, planning and testing is very important! Next, update the AD FS configuration by running the following Power.

Shell cmdlet on any of the federation servers in your farm, starting with the primary AD FS server in your farm, obviously you would need to adjust the “Alternate. Login. ID” and “Lookup. Forests” parameters to suite your particular requirements: Set- Adfs. Claims. Provider. Trust - Target. Identifier . We locate the “Microsoft Office 3.

Identity Platform” relying party trust and edit issuance transform rule number 1: The new rule should look like this: Lastly, we need to update our Dir. Sync attribute flow to ensure the correct attribute is synchronised. Run the miisclient. C: \Program Files\Windows Azure Active Directory Sync\SYNCBUS\Synchronization Service\UIShell”. Select the “Management Agents” tab, right- click to view the properties of “Active Directory Connector”.

Under “Configure Attribute Flow”, expand “Object Type: user” and find the “Data Source Attribute” of “< dn> ,s. AMAccount. Name,user. Principal. Name”. To edit it: Change the “Mapping Type” from “Advanced” to “Direct”Select the appropriate attribute (“mail” in my case) as the “Data source attribute”. Ensure that the “Metaverse attribute” is set to “user.

Principal. Name” and click “Edit” and then “OK” to save your changes. Once you have completed a successful synchronisation, you will be able to log into the Office 3. I’d like to conclude this post with the following. Unless you have a very specific requirements and/or constraints, I would recommend using UPN as your login attribute even if this means having to go through the process of changing all your user UPNs. In most environments this change will have little or no effect on other systems and may be the best approach.
