Server Component States in Exchange 2013 - Exchange Team Blog. Introduction In Exchange 2013 we introduced the concept of “Server Component States”. Server Component State provides granular control over the state of the components that make up an Exchange Server from the point of view of the environment it is running in. This is useful when you want to take an Exchange 2013 Server out of operation partially or completely for a limited time, but still need the Exchange services on the server to be up and running. One example of such a situation is when “Managed Availability” (MA) comes to the conclusion that a specific server is not healthy in some respects and therefore should be bypassed temporarily until the bottleneck has been identified and removed. MA does so by utilizing so-called “Offline Responders”. They are explained in some detail in Lessons from the Datacenter: Managed Availability.
Their counterpart are “Online Responders”, which bring the server back online when it is determined as being healthy again. About States and Requesters.

Microsoft first introduced the Edge Transport role as one of the five Exchange roles in Exchange 2007 and offered it again in Exchange 2010. The purpose of the Edge server role is to provide a solution for customers who require inbound SMTP connections to terminate in the perimeter network (DMZ), rather than in the internal network.
Since most inbound SMTP connections are unauthenticated, some security departments are uneasy at allowing these connections directly to internal resources (your Exchange servers). Edge transport servers allow these customers to deploy Exchange without having to buy an SMTP gateway appliance. For further security, computers running the Edge Transport role are not joined to the internal Exchange organization’s domain and cannot run any other Exchange roles. As the SMTP ingress point for the organization, Edge servers can act as your first line of defense for SMTP malware and denials of service. Exchange 2013 SP1 reintroduced the new 2013 Edge Transport role.
Does your environment need an Exchange 2013 Edge Transport server? Part 1: Reverse Proxy for Exchange Server 2013 using IIS ARR - Exchange Team Blog. For a long time, ForeFront TMG (and ISA before it) has been the go-to Microsoft reverse proxy solution for many applications, including Exchange Server. However, with no more development roadmap for TMG 2010 a lot of customers are looking out for an alternative solution that works well with Exchange Server 2013. The Windows team have added an additional component called Application Request Routing (ARR, or as Greg the pirate says, ARR!)
2.5 to the Internet Information Service (IIS) role, which enables IIS to handle reverse proxy requests. By using the URL Rewrite Module and Application Request Routing you can implement complex and flexible load balancing and reverse proxy configurations. There are two options when implementing this solution and each have their pros and cons, which I'll cover in three posts. Installation steps.Option 1 of implementing ARR as a reverse proxy solution for Exchange 2013 (this option is the simplest of the three configurations).
Prerequisites Installing ARR 1. Lessons from the Datacenter: Managed Availability - Exchange Team Blog. Monitoring is a key component for any successful deployment of Exchange. In previous releases, we invested heavily in developing a correlation engine and worked closely with the System Center Operations Manager (SCOM) product group to provide a comprehensive alerting solution for Exchange environments. Traditionally, monitoring involved collecting data and if necessary performing an action based on the collected data. For example, in the context of SCOM, different mechanisms were used to collect data via the Exchange Management Pack: Exchange Server 2013 Monitoring Goals When we started the development of Exchange 2013, a key focus area was improving end-to-end monitoring for all Exchange deployments, from the smallest on-premises deployment to largest deployment in the world, Office 365.
Bring our knowledge and experience from the Office 365 service to on-premises customers For nearly 6 years, the Exchange product group has been operating Exchange Online. Probes Monitors Responders.

This article is to provide you, the reader, the knowledge on how to properly create an Exchange 2013 Relay Connector. In Exchange 2013, I am utilizing a multi-role server that has both the Client Access Server and Mailbox Server roles. We’ll want to head to the mail flow section in the Exchange Administration Center (EAC) that you can access by going to Once in this mail flow section, we’ll click the tab called receive connectors which will allow us to see all receive connectors that exist.
As you can see, there are connectors for FrontendTransport and connectors for HubTransport. FrontEndTransport belongs to the Client Access Server Role and the HubTransport role belongs to the Mailbox Server role. Let’s take a look at the “Default B-E15DAG1” receive connector that belongs to the HubTransport role as well as the “Default Frontend B-E15DAG1” that belongs to the FrontendTransport role. Give the connector a name and be sure to choose Frontend Transport and Custom. Restoring a Mailbox from an Exchange Server 2013 Recovery Database.

In my last Exchange PowerShell post i looked at listing users hidden from the Global Address List. In this post we’ll look at listing all email addresses in use in Microsoft Exchange.
This can be useful if you are trying to add an email address and you get an error message because it is already in use somewhere. Although email addresses are most often associated with mailboxes, they can be found in other items too. In Exchange, Contacts and Distribution lists also have email addresses (as do Public Folders which we’ll look at another time). For that reason we can’t use Get-Mailbox which we used in the last post as that will limit our search to mailboxes only, instead we’ll be using Get-Recipient. If you pipe Get-Recipient into Get-Member you will see an EmailAddresses property which is exactly what we are after. As you can see below GM is an alias of Get-Member. The command is: Get-Recipient | GM Based on what we learnt in the last post we can start off with the command: Related Posts: 1. 2. Microsoft Exchange Server News - Tips - Tutorials.
Prevent open relays on Exchange Server. Open relays on corporate networks are a contributing factor to the volume of unsolicited e-mail currently flying around the Internet—and the presence of such relays is often unbeknownst to the owners of those networks. Are your e-mail servers vulnerable to mail relaying? In this edition of Security Solutions, Mike Mullins tells you how to determine if they are. Open mail relays—e-mail servers that allow third-party transmission of messages—are a significant contributing factor to the volume of unsolicited e-mail currently flying around the Internet. Spammers send millions of junk e-mail messages daily, and open mail relays make the process easier. However, most companies are unaware that spammers are taking advantage of the organization's e-mail servers for such nefarious purposes.
Depending on the version of Exchange server that your organization is running, you might be vulnerable to mail relaying. Defining the problem Checking your vulnerability 250 2.1.5 hacker@spammail.com. MX Lookup Tool - Check your DNS MX Records online - MxToolbox.
